If the data values are as shown in the picture I have attached, then the following should help.
Answer: 226.56 m²
Explanation:
We need to find the area of three rectangles and two triangles.
The triangles: 34.56 m²
A =
-> Since they are both congruent, we will skip dividing by two
A = B * H
A = 7.2 * 4.8
A = 34.56 m²
The rectangles: 192 m²
A = L * W
-> We have two that are congruent, and one that is not
A = 10 * 6 * (2, since there are two)
A = 120 m²
-
A = L * W
A = 7.2 * 10
A = 72 m²
-
72 m² + 120 m² = 192 m²
Total surface area:
34.56 m² + 192 m² = 226.56 m²
