Problema Solution
A rectangular carpet has a perimeter of 192 inches. The length of the carpet is 20 inches more than the width. What are the dimensions of the carpet?
Answer provided by our tutors
l= 20+w.
2(l+w)=192.
l+w=192/2.
l+w=96.
20+w+w=96.
2w=96-20.
2w=76.
w=76/2.
=38 inches.
l=w+20.
=38+20
=58 inches.
