Ответ:
10 m²
Step-by-step explanation:
1. First, find the area of the bigger (shaded) rectangle
4 x 3 = 12m²
2. Then, find the area of the door (white rectangle)
2 x 1 = 2m²
3. Because you are only finding the area of the shaded section, you need to subtract the area of the door from the shaded section
12m² - 2m² = 10m²
