A city park commission received a donation of playground equipment from a parents' organization. The area of the playground needs to be 256 square yards for the children to use it safely. The playground will be rectangular.

In a different plan, the sides can be of any length as long as the rectangular area remains 256 square yards. What dimensions of the rectangular area provide the least perimeter of fencing?    

You get the most area for the amount of perimeter if the figure is a square.    

sqrt(256) = 16     so the dimensions would be 16 x 16
