The picture below shows a variant of a famous paradoxical puzzle. On the left, we take two rectanglesof area 60, and cut each one into two pieces. On the right, we rearrange the four pieces, and put themtogether into a single rectangle of area 119. How could this be? Thoroughly explain why this is wrong mathematically (don't just say there is a gap, use numerical equations and stuff). If you need help, search "chessboard paradox" or "missing square puzzle".
