    Use Pythagoras theorem:-

    d^2 = a^2 + b^2

    - where d = length of the diagonal and a and b are the length and width of the rectangle.

    The diagonal = the positive square root of d^2.

    Use the pythagorean theorem: a² + b² = c²

    "a" and "b" are the lengths of the sides. "c" is the length of the diagonal.
