Well, depending on the requirements, it might be simpler - for example, if
we need the intersection anyway, and don't care at all about wether an
intersection is a rectangle.

That's why I think that statements like "OO is good/bad for shapes" is
nonsense - you need to know what a system is supposed *to do* to decide
wether and how to use an implementation technique like OO. If the
application needs to decide wether all rectangles are green, we might
actually prefer Prolog... ;)
