The formula for calculating the square area is: area = side length x side length. You can also use the formula s = a? Where s is the area and a is the side length. For example, the area of a square with a side length of 2 meters is 2 meters x2 meters = 4 square meters, which can be expressed as s = 2? =4。 Similarly, the area of a square with a side length of 5 cm is 5 cm ×5 cm = 25 square cm, which can be expressed as s = 5? =25。
Square meaning
A square is a regular polygon with four equal sides and four equal angles. The area of a square refers to the size of the plane area it contains, usually expressed in square meters, square centimeters, etc.
It can be seen that the formula for calculating the square area is very simple, just multiply it by its side length. In addition, the area formula can be calculated by knowing the diagonal length of the square, that is, area = diagonal length? /2。 However, because there is a specific mathematical relationship between the diagonal length and the side length of a square, the side length is usually used to calculate the area of a square.
Square application
Square is one of the most basic figures in geometry, which is widely used in life, such as architectural design, drawing standards, mathematical theory and so on. Therefore, learning the area calculation formula well will help to improve the application level of mathematics and geometry.
Area representation
Area is a quantity indicating the degree of a two-dimensional figure or shape or plane layer in a plane. A surface region is a simulation on a two-dimensional surface of a three-dimensional object. Area can be understood as the amount of material with a given thickness, which is necessary to form a shape model, or the amount of paint required to cover a surface with a single coating.
The area of a shape can be measured by comparing a fixed size shape with a square. In the International System of Units (SI), the standard unit area is square meters. A square area with an area of one meter and an area of three square meters will have the same shape as three such squares.
