Question: MINIMIZING FENCING COSTS The owner of the Rancho Grande wants to enclose a rectangular piece of grazing land along the straight portion of a river and then subdivide it using a fence running parallel to the sides. No fencing is required along the river. If the material for the sides costs $3/running yard and the material for the divider costs $2/running yard, what will be the dimensions of a 303,750 sq yd pasture if the cost of fencing is kept to a minimum?
