A rancher has 200 ft of fencing to enclose two adjacent rectangular corrals.

(A) write the area A of the corrals as a function of x.

(B) create a table showing possible values of x and the corresponding areas of the corral. Use the table to estimate the dimensions that will produce the maximum enclosed area.

(C) use a graphing utility to graph the area function. Use the graph to approximate the dimensions that will produce the maximum enclosed area.

(D) write the area function in standard form to find analytically the dimensions that will produce to maximum area.
