Question 537035: a farmer has 500 feet of fence with which to enclose a rectangular field. a striaght river bank will be used as a part of fencing on one side of the field.prove that area of the field is greatest when the rectangle is square? Answer by Alan3354(30993) (Show Source):
You can put this solution on YOUR website! It isn't.
Using 500 ft for 3 sides --> (500/3)^2 sq ft =~ 27,778 sq ft.
Making it 150 by 200 --> 30,000 sq ft.
So it's disproven.
