A portion of a wire 70 inches in length is bent to form a rectangle having the greatest possible area such that the length of the rectangle exceeds three times its width by 2 inches, and the dimensions of the rectangle are whole numbers. Find the length of the wire that is not used to form the rectangle.

The answer is
two inches. I need the work more than anything, though. An explanation of how you get that answer would be LOVELY. ^^; Thank you.
