Answer:
129 m²
Step-by-step 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
