Surface area of this shape please(step by step if you can)

Answer: 151.2 ft²
Step-by-step explanation:
The surface area, in this case, is the area of all the shapes given combined.
For the rectangles:
A = L * W
For the triangles:
A = [tex]\frac{L*W}{2}[/tex]
-> See attached
Now, we will add them altogether.
54 + 54 + 27 + 16.2 = 151.2 ft²
