Question

A playground is rectangular with a length of 7/8miles. If the area of the playground is 8/20 square miles what is the width?

Answer 1

Length - 7/8 miles
Area - 8/20 miles

We know from the equation that Area = Length x Width. 
We need to rearrange so that Width = Area ÷ Length
Width = 8/20 ÷ 7/8
           = 8/20 x 8/7 
           = 16/35
Therefore, the width will be 16/35 miles.
