Farmer Smith has 160 feet of fencing that she is using to make a rectangular enclosure for her chickens. She will use the side of an existing chicken coop as one side of the enclosure and use the fencing for the other three sides.
Which function gives the area A, in square feet, as a function of the length of one of the sides perpendicular to the existing coop?

a. A(x) = x(80 - 2x)
b. A(x) = x(80 - x)
c. A(x) = x(160 - 2x)
d. A(x) = x(160 - x)
