The document discusses optimizing the area of a rectangular field using 320 yards of fencing. It poses the problem of determining the shape of the field that maximizes the enclosed area given the fixed amount of fencing. It also provides a link to an online quiz about derivatives and graphing that contains problems requiring deep thought about concepts learned.
