Answer:
To find the area of a square, you need to know the length of one of its sides. The perimeter of a square is the sum of all of its sides, so if the perimeter of the square is 36 cm, and all sides of a square are equal in length, then each side of the square is 36 cm / 4 sides = 9 cm.
To find the area of the square, you can use the formula for the area of a square, which is A = s^2, where A is the area and s is the length of one side of the square. Substituting the value of 9 cm for s into this formula, we get:
A = s^2 = 9 cm^2 = 81 sq cm
So the area of the square is 81 square centimeters.
