473: Overlapping Squares

I might have posted this puzzle before.

What do your students think? Can they generalize it?
What is the overlapped area?

    1. Very nice.

      The problem reminds me of another:

      Suppose a rectangular cake has a single rectangular piece removed. Divide the remaining cake into two equal pieces with a single cut.

      (Cutting the cake "horizontally" through the middle gives one solution; but there is another!)
