Explanation:

Step1: Find small tile side lengths

The large square is 1 unit per side, divided into 6 columns and 5 rows. So each small tile's side lengths are $\frac{1}{6}$ units (horizontal) and $\frac{1}{5}$ units (vertical).

Step2: Calculate area of 1 small tile

Area = side length × side length, so $\frac{1}{6} \times \frac{1}{5} = \frac{1}{30}$.

Step3: Count shaded tiles, find total area

There are $4 \times 3 = 12$ shaded tiles. Total area = $12 \times \frac{1}{30} = \frac{12}{30} = \frac{2}{5}$.

Answer:

1. Each small tile has side lengths $\frac{1}{6}$ units and $\frac{1}{5}$ units.
2. The area of each small tile is $\frac{1}{30}$ square units.
3. The area of the shaded rectangle is $\frac{2}{5}$ square units.
