Answer:
Below
Explanation:
Separate into two sections. The top rectangle and the bottom rectangle.
The top rectangle is 5m tall and the width is 3m + 4m + 3m = 10m
So the area of the top rectangle is 5m x 10m = 50 m²
The bottom rectangle is 5m tall by 4m wide.
So the area of the bottom rectangle is 5m x 4m = 20 m²
Add the two areas together. 20m² + 50m² = 70m²
