**Reiny**, Friday, December 3, 2010 at 5:02pmlet the perimeter be P, where P is a constant

let the length be y and the width be x

2x + y = P

y = P - 2x

Area = xy

= x(P-2x) - Px - 2x^2

d(area)/dx = P - 4x

= 0 for a maximum area

4x = P

x = P/4

y = P - P/2 = P/2

So the long side should be half the perimeter, and the short side whould be a quarter of the perimeter.
