Calculator Dimensions and Rectangle

A = L * W

Then these equations are solved for L and W which are the length and width of the rectangle.

How to use the calculator

Enter the perimeter P and area A as positive real numbers and press "enter". The outputs are the width, length and diagonal of the rectangle. There are conditions under which this problem has a solution (see formulation of problem below).
