The management of a local Target store has decided to enclose an 800 square foot area outside the building for the garden display. One side will be formed by an external wall of the store, two sides will be constructed of pineboards costing $6 per foot and the side opposite the store will be constructed of fencing that costs $3 per foot. What dimensions of the enclosure will minimize the cost? Let x be the length of the side with fencing.
