Answer:
204 cm
Step-by-step explanation:
Triangle area = base × height ÷ 2
6×4÷2=12
Rectangle area = side 1 × side 2
6×10=60
5×10=50
There are 2 triangles, so make 12×2=24, 24 is the surface area of the triangles.
There are 2 rectangles with 5 in one side, so make 50×2=100 of area of this 2 rectangles
Now just sum the areas:
100+24+60= 204
