you are required to construct an enclosure for storing grain at a school. You must build a rectangular enclosure. To save material, you will use an existing wall of the kitchen as one of the four sides. The fence for the other three sides costs $15 and you must spend $10 to paint the portion of the wall that forms the 4th side of the enclosure. We have $180 to spend. what dimension will maximise the area of the enclosure you can build? And what is the domain?
