Question 251592: The length of a rectangle is four inches longer than twice its width. If both dimensions were increased by the length equal to its width, the perimeter would be three inches longer than 3/2 times its original perimeter.

"If both dimensions were increased by the length equal to its width"
Maybe it means all dimensions were increased by the original width
10w+8=3+3/2(6w+8)=new perimeter
w=7 old width
L=4+2*7=18 old length
14+36=50 old perimeter
new dimensions
nw=7+7=14
nl=18+7=25
28+50=78 new perimeter
