Answer:
I got 162?
Explanation:
I broke down each individual shape (7 rectangles and 2 triangles) and used each shapes surface area formula.
triangle surface area formula is 1/2*b*h, and there are 2 of the same triangles of the exact same size and 7 rectangles. 3 are same size rectangles, 2 are same size rectangles and the other 2 are different sized rectangles. Then add altogether.
