# What is the formula of the area of a rectangle, using the perimeter and the diagonal?

I know that the area of a rectangle is height * width;

the perimeter: 2*width + 2*height

and that the diagonal is square_root(height² + width²),

but is there a formula to calculate the area with only the perimeter and diagonal given?
