A city is building a fence around a rectangular playground. If the perimeter of the playground is 90 feet and the length of one side of the fence is 28 feet, what is the width of the playground?
a rectangle has 2 lengths of the same and 2 widths of the same. so your length is 28(56 for both sides) and subtraact it from 90 wich is yoru total perimite you get 34 and now devide by 2 and your widths will be 17 for both.
