Question

A rectangle is drawn so that the width is 3 feet shorter than the length. The area of the rectangle is 10 square feet. Find the length of the rectangle.

Answer 1

length=5ft
width= 2ft

10ft=l x w
w= l -3

10ft= l(l-3)
0= l^2 -3l-10
0= (l-5)(l+2)
l=5, l≠-2 (because a measurement can’t be negative)

w= 5-3
w=2
