Find the dimensions of the rectangle of maximum area that can be constructed with 500 m of fencing.
Find the maximum area.
~~~~~~~~~~~~~~~~~


A rectangle of the given perimeter P, which has maximum area, is a square with the side length 
one fourth of the perimeter. Its area is  %28P%2F4%29%5E2 square units.



In the given case, a rectangle of the given perimeter 0f 500 m (fencing), which has maximum area,
is a square with the side length of  500%2F4 = 125 m.


Its area is  %28500%2F4%29%5E2 = 125%5E2 = 15625 square meters.

Solved.
