want to form a rectangular pen of area 160 square feet. One side of the pen has an existing building, and the other three sides have a fence.  W is the length in feet, of the sides of rectangular perpendicular to the building.  Let L be the length, in feet, of the other side. Find a formula for the total amount of fence, F, needed in terms of W and L, express as an equation involving W and L, the requirement of total area 160 feet, then solve the equation for L.

Question

We want to form a rectangular pen of area 160 square feet. One side of the pen has an existing building, and the other three sides have a fence.  W is the length in feet, of the sides of rectangular perpendicular to the building.  Let L be the length, in feet, of the other side. Find a formula for the total amount of fence, F, needed in terms of W and L, express as an equation involving W and L, the requirement of total area 160 feet, then solve the equation for L.
