We need to enclose a field with a fence. We have 500 feet of fencing material and a building is on one side of the field so we won't need any fencing on that side. Determine the dimensions of the field that will enclose the largest area. Scan a copy of your work and email it. Only Calculus solutions will be accepted.

• x=250 ft, y=125 ft

• x=150 ft, y=200 ft

• x=125 ft, y=100 ft

• x=200 ft, y=150 ft
