Question

In the middle of a park there is a fenced off area in the shape of the fence says is a square. If the area of the fenced off portion is 225 yd.², what is the perimeter of the fence is?

Answer 1

Answer:

Step-by-step explanation:

The formula for the area of a square is A = x^2, where x is the length of one side.  Equivalently, x^2 = A.

Here x^2 = 225 yd^2.  Taking the positive square root of both sides, x = 15 yd.

Thus, the perimeter of the square area enclosed by the fence is

P = 4(15 yd) = 60 yd
