Calculate the area of each compound shape on the grid.

To find the area of each compound shape, we first need to determine the size of one square on the grid.

Step 1: Find the area of one small square.
The image shows that 3 grid squares equal 3 cm in length.
* Length of 3 squares = 3 cm
* Length of 1 square = $3 \text{ cm} \div 3 = 1 \text{ cm}$

Since each small square is 1 cm wide and 1 cm tall, the area of one small square is $1 \text{ cm}^2$.

Now, we just need to count how many small squares make up each lettered shape to find its total area.

Shape A:
* Count the squares: There are 4 squares.
* Area = $4 \times 1 \text{ cm}^2 = 4 \text{ cm}^2$

Shape B:
* Count the squares: There are 5 squares.
* Area = $5 \times 1 \text{ cm}^2 = 5 \text{ cm}^2$

Shape C:
* Count the squares: There are 8 squares.
* Area = $8 \times 1 \text{ cm}^2 = 8 \text{ cm}^2$

Shape D:
* Count the squares: There are 8 squares.
* Area = $8 \times 1 \text{ cm}^2 = 8 \text{ cm}^2$

Shape E:
* Count the squares: There are 10 squares.
* Area = $10 \times 1 \text{ cm}^2 = 10 \text{ cm}^2$

Shape G:
* Count the squares: There are 16 squares.
* Area = $16 \times 1 \text{ cm}^2 = 16 \text{ cm}^2$

Shape H:
* Count the squares: There are 12 squares.
* Area = $12 \times 1 \text{ cm}^2 = 12 \text{ cm}^2$

Shape I:
* Count the squares: There are 20 squares.
* Area = $20 \times 1 \text{ cm}^2 = 20 \text{ cm}^2$

Shape L:
* Count the squares: There are 24 squares.
* Area = $24 \times 1 \text{ cm}^2 = 24 \text{ cm}^2$

*(Note: Shapes F, J, and K are cut off in the image, so their areas cannot be calculated.)*

Final Answer:
A: 4 cm²
B: 5 cm²
C: 8 cm²
D: 8 cm²
E: 10 cm²
G: 16 cm²
H: 12 cm²
I: 20 cm²
L: 24 cm²
