Question
A farmer wants to fence in a rectangular plot of land adjacent to the south
wall of his barn. No fencing is needed along the barn, and the fencing along the east side
of the plot is shared with a neighbor who will evenly split the cost of that portion of the
fence. Fencing costs $30 per linear foot to install and the farmer only wants to spend
$9000. Let x be the length of fence that's shared with the neighbor. Find a formula for
the area A(x) enclosed by the fence and the barn. What is the maximum possible area
enclosed?
