More about the area
General information
Area is a quantity geometric figure in two-dimensional space. It is used in mathematics, medicine, engineering and other sciences, such as computing cross section cells, atoms, or tubes such as blood vessels or water pipes. In geography, area is used to compare the sizes of cities, lakes, countries, and other geographic features. Population density calculations also use area. Population density is defined as the number of people per unit area.
Units
Square Meters
Area is measured in SI units in square meters. One square meter is the area of a square with a side of one meter.
Unit square
A unit square is a square with sides of one unit. The area of a unit square is also equal to one. In a rectangular coordinate system, this square is located at coordinates (0,0), (0,1), (1,0) and (1,1). On the complex plane the coordinates are 0, 1, i And i+1, where i- imaginary number.
Ar
Ar or weaving, as a measure of area, is used in the CIS countries, Indonesia and some other European countries, to measure small urban objects such as parks, when a hectare is too large. One are is equal to 100 square meters. In some countries this unit is called differently.
Hectare
Real estate is measured in hectares, especially land plots. One hectare is equal to 10,000 square meters. It has been in use since the French Revolution, and is used in the European Union and some other regions. Just like the macaw, in some countries the hectare is called differently.
Acre
IN North America and Burma, area is measured in acres. The hectares are not used there. One acre is equal to 4046.86 square meters. An acre was originally defined as the area that a farmer with a team of two oxen could plow in one day.
Barn
Barns are used in nuclear physics to measure the cross section of atoms. One barn is equal to 10⁻²⁸ square meters. The barn is not a unit in the SI system, but is accepted for use in this system. One barn approximately equal to area cross-section of a uranium nucleus, which physicists jokingly called “as huge as a barn.” Barn in English is “barn” (pronounced barn) and from a joke among physicists this word became the name of a unit of area. This unit originated during World War II, and was liked by scientists because its name could be used as a code in correspondence and telephone conversations within the Manhattan Project.
Area calculation
The area of the simplest geometric figures is found by comparing them with a square famous square. This is convenient because the area of the square is easy to calculate. Some formulas for calculating the area of geometric figures given below were obtained in this way. Also, to calculate the area, especially of a polygon, the figure is divided into triangles, the area of each triangle is calculated using the formula, and then added. The area of more complex figures is calculated using mathematical analysis.
Formulas for calculating area
- Square: square side.
- Rectangle: product of the parties.
- Triangle (side and height known): the product of the side and the height (the distance from this side to the edge), divided in half. Formula: A = ½ah, Where A- square, a- side, and h- height.
- Triangle (two sides and the angle between them are known): the product of the sides and the sine of the angle between them, divided in half. Formula: A = ½ab sin(α), where A- square, a And b- sides, and α - the angle between them.
- Equilateral triangle: side squared divided by 4 and multiplied by square root out of three.
- Parallelogram: the product of a side and the height measured from that side to the opposite side.
- Trapezoid: the sum of two parallel sides multiplied by the height and divided by two. The height is measured between these two sides.
- Circle: the product of the square of the radius and π.
- Ellipse: product of semi-axes and π.
Surface Area Calculation
You can find the surface area of simple volumetric figures, such as prisms, by unfolding this figure on a plane. It is impossible to obtain a development of the ball in this way. The surface area of a ball is found using the formula by multiplying the square of the radius by 4π. From this formula it follows that the area of a circle is four times less area surface of a sphere with the same radius.
Surface areas of some astronomical objects: Sun - 6,088 x 10¹² square kilometers; Earth - 5.1 x 10⁸; Thus, the surface area of the Earth is approximately 12 times smaller than the surface area of the Sun. The Moon's surface area is approximately 3.793 x 10⁷ square kilometers, which is about 13 times smaller than the Earth's surface area.
Planimeter
Area can also be calculated using special device- planimeter. There are several types of this device, for example polar and linear. Also, planimeters can be analog and digital. In addition to other functions, digital planimeters can be scaled, making it easier to measure features on a map. The planimeter measures the distance traveled around the perimeter of the object being measured, as well as the direction. The distance traveled by the planimeter parallel to its axis is not measured. These devices are used in medicine, biology, technology, and agriculture.
Theorem on properties of areas
According to the isoperimetric theorem, of all figures with the same perimeter, the circle has the largest area. If, on the contrary, we compare figures with the same area, then the circle has the smallest perimeter. The perimeter is the sum of the lengths of the sides of a geometric figure, or the line that marks the boundaries of this figure.
Geographical features with the largest area

City: New York is the city with the largest area of 8683 square kilometers. The second largest city by area is Tokyo, occupying 6993 square kilometers. The third is Chicago, with an area of 5,498 square kilometers.
City Square: The largest square, covering 1 square kilometer, is located in the capital of Indonesia, Jakarta. This is Medan Merdeka Square. The second largest area, at 0.57 square kilometers, is Praça doz Girascoes in the city of Palmas, Brazil. The third largest is Tiananmen Square in China, 0.44 square kilometers.
Lake: Geographers debate whether the Caspian Sea is a lake, but if so, it is the largest lake in the world with an area of 371,000 square kilometers. The second largest lake by area is Lake Superior in North America. It is one of the lakes of the Great Lakes system; its area is 82,414 square kilometers. The third largest lake in Africa is Lake Victoria. It covers an area of 69,485 square kilometers.

Choose a tape measure or tape measure. Choose a tape measure or measuring tape marked with centimeters (cm) or meters (m). This device will make it easier to calculate the area in square meters, since they were developed in the same measurement system.
- If you can find a tape measure in feet or inches, measure the area using the available units of measurement, and then proceed to the step that describes how to convert other units of measurement to square meters.
Measure the length of the area you have chosen. A square meter is a unit of measurement for the area or size of a two-dimensional object such as a floor or field. Measure the length of one side from one corner to the other and write down the result.
- If the length is more than one meter, then count both meters and centimeters. For example, 2 meters 35 centimeters.
- If the object you are measuring is not a rectangle or square, then read the third section of this article - “Measuring the area of complex shapes.”
If you can't measure the length at once, do it in stages. Lay out the tape measure and make a mark where it ends (for example, 1 meter or 25 centimeters), then lay it out again and start from the marked area. Repeat until you have measured the entire length. Then add all the measurements together.
Measure the width. Use the same tape measure to measure the width of the object. You need to start measuring by placing the tape measure at an angle of 90º in relation to the length of the object that you have already measured. That is, two lines of a square adjacent to each other. Also write down the resulting numbers on paper.
- If the measured length is slightly less than one meter, then round to the nearest centimeter when you take measurements. For example, if the width is slightly larger than the 1 meter 8 centimeters mark, then simply write down “1 m 8 cm.” and don't count millimeters.
Convert centimeters to meters. Usually measurements cannot be made exactly in meters. You will get indicators in both meters and centimeters, for example “2 meters 35 centimeters”. 1 centimeter = 0.01 meters, and therefore you can convert centimeters to meters by moving the decimal point 2 digits to the left. Here are some examples.
- 35cm = 0.35m, so 2m 35cm = 2m + 0.35m = 2.35m
- 8cm = 0.08m, so 1m 8cm = 1.08m
Multiply the length by the width. Once you convert all measurements to meters, multiply the length by the width to get the area of the object being measured. Use a calculator if necessary. For example:
- 2.35m x 1.08m = 2.538 square meters (m2).
Round up. If you get a lot of numbers after the decimal point, for example, 2.538 square meters, then round, for example, to 2.54 square meters. It's likely that you didn't measure to the nearest millimeter, so the final numbers won't be accurate anyway. In most cases we round to the nearest centimeter (0.01m). If you need more accurate measurements, read this material.
- Whenever you multiply two numbers with the same unit of measurement (for example, meters), the answer must be written in the same unit of measurement (m 2, or square meters).
