Question

A farmer has 1,200 feet of fencing and wants to fence off a rectangular field that borders a straight river. He needs no fence along the river. Write the function that will produce the largest area if x is the short side of the rectangle.

Answer 1

you would need to know the longest side of the rectangles length

Answer 2

I don't think you would, if its a rectangle, then the two short sides would be those that intersect with the river and you would only need one long side. so you would need to break the 1200 into three parts to create the largest area possible. how to do that, i don't know.
