Question and answer
The length of a rectangle is 3 times its width. If the length were increased by 2 inches and the width by 1 inch, the new perimeter would be 62 inches. What is the width and length of the rectangle?
l=3b.Now 2( (l+2)+b+1)=62.Now sub for l.Then 2(3b+2+b+1)=62.Hence 8b+6=62.8b=56.Hence b=7 and l=21
