Question

How do I get the surface area of the shape

Answer 1

129 m²

Explanation:

Let's start by finding the areas of the triangles on the sides:

4×6÷2=12 (height times base divided by two)

Then we multiply by 2 as there are 2 of them

12×2=24

Then we find the areas of the rectangles:

5×7=35

35×3=105 (there are three)

Finally we add them:

105+24=129 m²
