The length of a rectangular floor is 2 feet more than its width. The area of the floor is 168 square feet. Kim wants to use a rug in the middle of the room and leave a 2 foot border of the floor visible on all sides. What should the length (the longer side) of the rug be?

x(x+2) = 168

x = 12

x + 2 = 14

The longer side should leave 2 feet at each end.

14 - 4 = 10
