Interesting one! If a rectangle has width w and height h, 1) the area a = wh 2) the perimeter p = 2w + 2h From 1), w=a/h Substituting into 2) p = 2a/h + 2h Multiplying by h pH = 2a + 2h2 Rearranging 2h2 - pH + 2a = 0 This is a quadratic equation in h. Factorising, using the standard quadratic formula, h = (p ± sqrt(p2 - 16a))/4 The two solutions to this will be the two dimensions.

Let P be perimeter, A is area, L is length, and W is width.A = L x W, P = 2L + 2W; you know P and W, so L = (P - 2W)/2and A = W x (P - 2W)/2

We know:2(w+h)=pw*h=aTherefore:w=a/h2(a/h + h)=p2(a + h^2)=p*h2*h^2 - p*h + 2a = 0which can be solved for h using the quadratic formula (see http://en.wikipedia.org/wiki/Quadratic_equation):(-b +/- sqrt(b^2 - 4ac)) / 2aTherefore:h=(p +/- sqrt(p^2 - 16a)) / 2aOnce we have h, we can get w easily by calculating a/h. Note that there may be two possible values for h (because of the +/- in the quadratic formula), so there may be two values of w to correspond with each of these.
