Problema Solution
A farmer has 160ft of fence to enclose a four sided field. He is going to use all or part of one side of his barn so he can make his field as big as possible. If his barn is 100 ft long, find the maximum area of his field.

If the barn has to be used on the whole side of the filed, 100 ft of fencing goes to cover its opisie side.then only 60 ft left for the two sides.
The dimensions are therefore 30 ft * 100 ft =3000 sq.ft.
Maximum area of field =3000 sq.ft.
