a. If the area of a square is 625 cm squared​, what is its​ perimeter? b. If the perimeter of a square is 76 cm​, what is its​ area?

Answer 1

Since all sides of a square are equal and area = length * width, then the length of a side of a square will be equal to the square root of the area. The perimeter would be four times the length of a side.

Since the perimeter is four times the length of a side, we can determine the measure of one side, then square it to get the area.
