Question

The perimeter of a rectangular playground is 86 feet, the width of the playground is 15 feet, what is the length

Answer 1

The length is 28ft. W=15 so you’d subtract 30 from 86 and get 56. Then divide 56 by 2 and get 28 which is the length. You can check this by adding 15+15+28+27 together and see if it equals 86 which it does.
