II-A 7.28

I don't understand how the dominoes function or how to solve the question really... I am confused about what the dominoes are, is each one identical, or do they look different, or are we just essentially coloring the grid with black and white dominoes.

Thanks

You can assume the dominoes are identical. The important thing is that they are rectangles with dimensions $1 \times 2$.
