To find the length of one side of a square when given its perimeter, you can use the formula for the perimeter of a square, which is:
Perimeter = 4 × side length
In this case, we know that the perimeter is 36. So we can set up the equation:
36 = 4 × side length
To find the length of one side, we need to solve for the side length. We can do this by dividing both sides of the equation by 4:
side length = 36 ÷ 4
When we perform the division:
side length = 9
Therefore, the length of one side of the square is 9 units.
