How do you find perimeter of a square with area of 324?

Answer 1

Say one of the sides is s. Because it is a square, both the length and width (both sides) are s.

Area = length x width

So 324 = s x s, or 324 = s2.

So s is equal to the square root of 324.

Because perimeter is the sum of the sides, add s + s + s + s.
