Question

I am a rectangle, and my area is 80 square inches. My width is 2 inches shorter than my length. What is my perimeter?

Answer 1

Area=l*b=l*(l-2)=80(given)

so, l^2 - 2l =80
   l^2 - 2l - 80=0
   l=10 or -8

l=10,b=10-2=8
perimeter=2(l+b)=2(18)=36

Answer 2

8 of width, 10 of length, now 2(8) + 2(10)= 36 Inches
