Question

The perimeter of a rectangular playground is 500 ft. If the width is 100 ft, what is the length of the playground?

Answer 1

The perimeter of a rectangle is P = 2l + 2w.

You are given P = 500 ft. and w = 100ft. We need to find l.

2l + 2(100) = 500

2l + 200 = 500

2l = 300

l = 150 ft.
