Maximizing construction costs The management of the UNICO department store has decided to enclose an 800 ft^2 area outside the building for displaying potted plants and flowers. One side will be formed by the external wall of the store, two sides will be constructed of pine boards, and the fourth side will be made of galvanized steel fencing. If the pine board fencing cost $6 / running foot and the steel fencing cost $3 / running foot, determine the dimensions of the enclosure that can be erected at minimum cost.
