Sergio [31]

Answer:

174.7

Step-by-step explanation:

Let's find the area of the two triangles

(2)(1/2)(11*7.7) = 84.7

Back rectangle

3 x 11 = 33

Front facing rectangle

3 x 9 = 27

Bottom rectangle

3 x 10 = 30

Total = 84.7 + 33 + 27 + 30 = 330 + 60 + 30 = 420

If my answer is incorrect, pls correct me!
