Question 1138952: Farmer Ed has 3,000 meters of fencing, and wants to enclose a rectangular plot that borders on a river. If Farmer Ed does not fence the side along the river, what is the largest area that can be enclosed?
The largest area that can be enclosed is__ square meters Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! The two sides are x and the length is 3000-2x (draw this)
The area is x(3000-2x)=-2x^2+3000x
That maximum is where x=-b/2a or -3000/-4 or 750 m
so the sides are 750 m and the length is 1500 m with maximum area of 1,125,000 m^2
