The length of a side of the square is 9 centimeters. The length of the diagonal is 12.73 centimeters.
What is the length of the side and diagonal?
A square is an object that has four sides of equal length. A square has two diagonals that biscect each other at 90°. The diagonals are of equal length. The diagonals of a square divide the square into two right triangles.
Area of a square = length²
Length = √area
√81 = 9cm
Pythagoras theorem can be used to determine the length of the diagonal.
The Pythagoras theorem: a² + b² = c²
Where:
- a = length
- b = base
- c = hypotenuse
9² + 9²
= 81 + 81
= √162 = 12.73 cm
