How can you divide the board into exactly $2$ equally-shaped and sized pieces such that it fits the hole?
Bonus: Can you do the same problem in $3$ pieces, such that one of the pieces of the board has the sides of a square? If no, then what is the minimum number of pieces you have to make to do so?
Checkmark goes to the one who solves both parts :) .
Edit :- Forgot to mention that in the case of $3$ pieces, the square piece will be one of them, and the other two pieces will be equally-shaped and sized.
