Question

What is the length of a side of a square whose perimeter is 36cm?

Answer 1

The perimeter of a square is the sum of the lengths of its four sides.

Let the length of a side of the square be x.

Therefore, the perimeter of the square is 4x.

Given that the perimeter is 36 cm, we can set up the equation:

4x = 36

Simplifying the equation:

x = 36/4

x = 9

Therefore, the length of a side of the square is 9 cm.
