The perimeter of a square is 40 yards. What is its area?

100 yds^2

Step-by-step explanation:

To find the area of a square, we need to know the length of one side of the square. Since the perimeter is 4 times the length of one side, or 4s, and since 4s = 40 yds, s must be 10 yds.

Then the area of the square is (10 yds) ^2 = 100 yds^2.
