Hotel room that has a place for guests to Stationery. Someone in this Stationery seems to open a hole in the crank. Stationery in exactly the same shape I want to isolate the two perforated sheets. Stationery is a written grid square. If the same form, it may even reverse to the other.

Notes on Puzzle
Some mean person has cut a hole out of the hotel stationary! You have to cut the paper into two pieces so that the pieces are the same shape. The paper is marked with a grid, so you just mark where on the grid to cut. The hole is small (only 2 squares in the grid) so cutting it is pretty straightforward.
