18 meters²
Step-by-step explanation:
You can divide the shape into a square and right triangle, see the attachment :)
The area of the square is the length times the width. So,
3 · 3 = 9
The area of the square is 9 m².
The triangle's area is the base times the height divided by 2. So,
6 · 3 = 18
18 / 2 = 9
The triangle has an area of 9 m².
Add these together.
9 + 9 = 18
The area is 18 meters².
