A landscape architect wishes to enclose a rectangular garden on one side by a brick wall costing $30/ft and on the other three sides by a metal fence costing $20/ft. If the area of the garden is 2,000 ft2, find the dimensions of the garden that minimize the cost.

?= (ft of brick wall)

?= (ft of length of adgesent side of brick wall)
