A farmer can use one mile of a straight river as one border of an animal pen. What is the least amount of fencing needed to enclose a region of one square mile?
I'm guessing it is a semi circular pen. But I am not sure how to show that that is the minimum. I know its smaller than the triangle and the square.
Any advice on how to go about this?
