13. Suppose you want to use 600 meters of fencing to surround two identical adjacent rectangular

plots. Write a function for the combined area of the plots with respect to the length of one of the

sides (x). What dimensions would produce the maximum

combined area?

What is that maximum

combined area?

14. A farmer with 1000 meters of fencing wants to enclose a rectangular plot that borders along a

straight river. If the farmer does not want to fence along the river, what is the largest area that can

be enclosed? What dimensions produce that area?
