Build a rectangular pasture with 40 m of fence, using a barn wall or a river as one side. Dragging a corner post moves a point on the graph of the area S(x) = x(40 − 2x) and changes the number of sheep, and on each piece of land you predict and then find where the area is largest or smallest within the range of x set by the wall length and the land depth.
