A rectangular area adjacent to a river is to be fenced in; no fence is needed on the river side. The enclosed area is to be square feet. Fencing for the side parallel to the river is per linear foot, and fencing for the other two sides is per linear foot; the four corner posts are apiece. Let x be the length of one of the sides perpendicular to the river.
