A rectangle is drawn so that the width is 3 feet shorter than the length. The area of the rectangle is 18 square feet. Find the length of the rectangle.

The answer is

Step-by-step explanation:

Area of a rectangle = l × w

where

l is the length of the rectangle

w is the width

Area = 18 ft²

the width is 3 feet shorter than the length is written as

w = l - 3

Substitute it into the above equation

18 = l( l - 3)

l² - 3l - 18 = 0

( l + 3)( l - 6 ) = 0

l + 3 = 0 l - 6 = 0

l = - 3 l = 6

Since the length is positive, the length of the rectangle is 6 feet
