A playground is in the shape of a square. If the perimeter of the playground is 40 feet, what is the length of the diagonal across the playgroun?

14.14 ft.

Step-by-step explanation:

The formula for a diagonal is x√2 where x represents the length of one side. Since the perimeter of the playground is 40 ft. and is in the shape of a square, we know that each side must be 10 ft. long. Now we can input the values and solve.

10√2 = 14.14
