Removed Square Problems (5 × 3 grid)We answer this question Here is a 5 × 3 grid, with a unit square removed. Now, it has an even number of unit squares. Is it tileable with 2 × 1 tiles? The grid has 15 squares. Remove 1 = 14 squares. This is even, so it might be possible. For this image, it is possible But, let’s modify the image Is the following region tileable with 2 × 1 tiles? Now, if we try this – our region is tileable Now, let’s answer this Is the following region tileable with 2 × 1 tiles? If we tile it, it would be like So, we are missing two tiles Thus, our region is not tileable So, the even area rule is not complete To understand how to do this, we have to look at the grid not as a blank shape, but as a checkerboard.
