To find the area of the given shape, we can treat it as a right triangle combined with a rectangle. Let's break it down:

1. The shape has two parts: a rectangle and a right triangle.

   • The rectangle has dimensions: 9 m by 2 m.
   • The right triangle has a base of 9 m and a height of 5 m.

2. Area of the rectangle: $\text{Area of rectangle} = \text{length} \times \text{width} = 9 \, \text{m} \times 2 \, \text{m} = 18 \, \text{m}^2$

3. Area of the triangle: $\text{Area of triangle} = \frac{1}{2} \times \text{base} \times \text{height} = \frac{1}{2} \times 9 \, \text{m} \times 5 \, \text{m} = 22.5 \, \text{m}^2$

4. Total area: $\text{Total area} = \text{Area of rectangle} + \text{Area of triangle} = 18 \, \text{m}^2 + 22.5 \, \text{m}^2 = 40.5 \, \text{m}^2$

So, the total area of the shape is 40.5 m².

Tip: When calculating the area of a compound shape, break it down into simpler shapes (like rectangles, triangles, etc.) and find the area of each part separately.
