Algebra problem finding the length and width when the area is give.

Question

The area is 108^2 and the width is 3 inches longer than the length, what equation represents the area of this rectangle?

Answer 1

Hello Crystal,

Let's assign some terms for an equation to solve the problem, fair enough?

Let length be x <----- the length is not given

Let width be x + 3 <-----the width is 3 inches longer than the length

The formula or equation for determining the area of a rectangle is as follows:

A = L x W Where A equals area, L equals length, and W equals width.

Given the fact that the area is 108^2 the equation would be as follows:

108^2 = x * x + 3

108^2 = x^2 + 3

Can you solve from here?
