Question

A rectangular park has an area of 6 square miles. The width of the property is 3/8 the length of the property. What is the width of the property?

Answer 1

Area = width * length

if width = 3/8 length ⇒ length = 8/3 width

area = width * 8/3 width = 8/3 width² = 6

width² = $\frac{6*3}{8} = \frac{3 * 3}{4} = \frac{9}{4}$

width = $\sqrt \frac{9}{4} = \frac{3}{2}$
