Answer:
228.4
Step-by-step explanation:
Both triangle surface:
4x4.6 and then divide by 2 = 9.2
That will be the surface for one triangle
But there are two triangles so we times that by 2
That will be 18.4
Both big rectangle surface: (the top and bottom ones)
15x5=75
But we have two rectangles
So we times that by two and the answer will be =150
Smaller rectangle: (the one between two triangles)
4x15=60
Okay, now we add them all up, the triangles and rectangles
60+150+18.4=228.4
