You are fencing a rectangular puppy kennel with 25 ft. of fence. The side of the kennel against your house does not need a fence. This side is 9 ft. long. Find the dimensions of the kennel.
w = width l = length = 9 Perimeter = 2w+2l Normally you would face the whole perimeter but "the side of the kennel against your house does not need a fence." So you actually fence 2w+1l
