The area of a rectangular piece of land is 30.6 square miles. If the width of the land is 4.5 miles, how much longer is the length of the land than the width?

Question

 help pleaseeeeeeeeee

Answer 1

Area of Rectangle = Length x Width = L x W = 30.6 mi²

 

We know the width, W = 4.5 mi. So:

 

L x W = 30.6 mi²

L x (4.5 mi) = 30.6 mi²

 

Divide both sides by 4.5 mi

 

L = 30.6/4.5

L = 6.8 mi

 

The question is asking how much longer is the length.

 

How much longer = L - W = 6.8 - 4.5 = 2.3 mi

 

The length is 2.3 mi longer than the width.
