Based on the image, calculate the areas S1 and S5

Based on the image we can determine the sides of the rectangles and calculate area.
Area S1: The sides are 3 cm and 6 cm.
Area S5: The sides are 2 cm and 7 cm.

Now, let's calculate the areas:

Area S1:

$$S_1 = 3 \text{ cm} \cdot 6 \text{ cm} = 18 \text{ cm}^2$$

Area S1: 18 cm²

Area S5:

$$S_5 = 2 \text{ cm} \cdot 7 \text{ cm} = 14 \text{ cm}^2$$

Area S5: 14 cm²
