7-108.

If you know the number of shaded tiles, and you know the area of each shaded tile, how can you find the total area of the shaded tiles?

1 square foot · 28 shaded tiles = 28 square feet

Use the tiles to determine the length and width of the large rectangle.

Total unshaded area = total area − shaded area
