A rancher plans to use an existing stone wall and the side of a barn as a boundary for two adjacent rectangular corrals. Fencing for the perimeter costs 10 per foot. To separate the corrals, a fence that costs 8 per foot will divide the region. The total area of the two corrals is to be 7,000 square feet.
