<PRE><B>Question 303062</B>
A rectangular walkway is 18 feet longer than it is wide. If the area of the walkway is 88 square feet, find the length and the width.


let the width be x

the length will be x+18

The area = L*W

x(x+18)=88

x^2+18x=88

x^2+18x-88=0

X^2+22x-4x-88=0

x(x+22)-4(x+22)=0

(x+22)(x-4)=0

x= -22 OR x=4

Thw width cannot be begative

so the width is 4 feet
