A rectangle has an area of 12 square inches, and the rectangle's length is 11 inches greater than its width. what is the length and width?

Question

_{i need to know the length and width} 

Answer 1

A=lw

w=width

w+11=length

12=(w+11)(w)

12=w^2+11w

w^2+11w-12=0

(w+12)(w-1)=0

w-1=0

w=1

w+11=12

width=1 inch

length=1+11=12 inches

Answer 2

Lets assign W = width and L = Length 

 

Area = 12sq Inches

 

L - W = 11

 

As the length is 11 inches longer than the width, therefore the L = 12 and W = 1.

 

Hope this helps.
