I have a question I really need help with. It says...a rectangular pen is made with 100 m of fencing. It has a picture of a rectangle. It says let x = the shorter side. I need to figure the maximum area of the pen. I was able to do the problems with only 3 sides, but I am not sure how to do one with 4 sides and no additional information. Can anyone help?
