Square - perimeter and area
C = 4 * a
A = a * a
A = area
P = perimeter
a = side "a"
WHAT IS IT ?
A square is a four-sided polygon, or quadrilateral, with all sides of equal length and all internal angles equal to 90 degrees. It is a special type of rectangle and rhombus. The properties of a square include equal diagonals that bisect each other at right angles and divide the square into two congruent isosceles right triangles. The area of a square can be calculated using the formula: Area = side length², and the perimeter can be calculated as: Perimeter = 4 * side length. Squares are fundamental shapes in geometry and are used in various applications in mathematics, design, and architecture.
CALCULATION:
EXAMPLE:
The side of the square is, for example, 8 cm. Thus, a = 8.
perimeter of the square:
We use the formula
C = 4 * a
thus
C = 4 * 8
C = 32 cm
area of the square:
We use the formula
A = a * a
thus
A = 8 * 8
A = 64 cm²
