Answer:
41.7 square meters
Explanation:
First, rectangle A:
4 x 6 = 24 square meters
Second, rectangle B:
We know the length of this section is 3.5m. For the height/width, we can look at rectangle C. The height of C is 3.8m, and we see the part of C that is NOT part of B is 2m long. So we subtract 2 from 3.8 to find the height of B.
3.8 - 2 = 1.8m
Then, for the area of B:
3.5 x 1.8 = 6.3 square meters
Third, rectangle C:
3 x 3.8 = 11.4 square meters
Add up areas of A, B, C:
24 + 6.3 + 11.4 = 41.7 square meters
