Accepted Solution

A:
if you are given a certain length of wire the biggest area you can fend up is a circle, 2nd a square.  For the rectangle to have the biggest area,the difference between the 2 sides must be the minimum,  it must approaches a square then we have         2(l +w)   =    200                                   l + w   =     100 the  dimensions   are    49 & 51multiply    49 by  51  =  2499 sq. m, will give the biggest area, any other      combinations will give a smaller area if you considered decimal numbers between
