Given one set of pentominoes:
Use five (different) pentominoes to build a bridge with a rectangular outer edge.
Magnify this bridge with factor 2.
To build this similar bridge use a set of pentominoes and two sets of tetrominoes.
Extra rule: the same tetrominoes may not touch each other, not even with just a corner
The pentominoes and tetrominoes must lie in a single plane.
Try to maximise the enclosed area.
