Question 381279: given 300 meters, what is the maximum rectangular area that can be fenced off?

You can put this solution on YOUR website! The optimal area of a rectangle with a given perimeter is a square (this can be proven using introductory calculus). Therefore the side length of such a square is 75 m, so the area is (75 m)^2 = 5625 m^2.
