Answer:
b = 5/4 miles
Explanation:
Length of a rectangular playground, l = 1/2 miles
Area of the playground, A = 5/8 square miles
We need to find the width of the playground. We know that, the area of a rectangular shape is given by :
A = l×b, here b is the width of the playground.
![b=(A)/(l)\\\\b=((5)/(8))/((1)/(2))\\\\b=(5)/(4)\ \text{miles}](https://img.qammunity.org/2021/formulas/mathematics/college/a13tbxskbjvgk1swqvcxf9s8pe6yd84gsq.png)
So, the width of the playground is 5/4 miles.
