Similar Hole Problems

In 1974 Jean Meeus proposed the problem 'to construct an area containing an interior hole of the same shape' for sets of polyominoes and polyiamonds. If the total area of the set of pieces is A then we require to find integers x, y and n such that A = n(x²-y²) in which case we have a pattern of area nx² with a similar hole of area ny². It is also possible to look for multiple congruent figures with similar holes.
