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
Olegator [25]
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}
