To find the area of the given figure, we must calculate the area of the parallelogram and adjust it by accounting for the additional and subtracted triangular areas.

Step 1: Identify Key Shapes

1. Parallelogram:

   • A parallelogram's area is $A_{\text{parallelogram}} = \text{base} \times \text{height}$.
   • Here, the parallelogram's base is $9 \, \text{m}$ (long leg of the triangle), and the height is $5 \, \text{m}$ (short leg of the triangle).
   • Therefore: $A_{\text{parallelogram}} = 9 \times 5 = 45 \, \text{m}^2.$

2. Additional Triangles:

   • Two triangles with base $8 \, \text{m}$ and shared height $5 \, \text{m}$ are attached to the top of the parallelogram.
   • The area of one triangle is: $A_{\text{triangle}} = \frac{1}{2} \times \text{base} \times \text{height} = \frac{1}{2} \times 8 \times 5 = 20 \, \text{m}^2.$
   • Since there are two such triangles, their total area is: $A_{\text{added triangles}} = 2 \times 20 = 40 \, \text{m}^2.$

3. Subtracted Triangle:

   • Inside the parallelogram is a right triangle with base $9 \, \text{m}$ and height $5 \, \text{m}$.
   • Its area is: $A_{\text{subtracted triangle}} = \frac{1}{2} \times 9 \times 5 = 22.5 \, \text{m}^2.$

Step 2: Calculate the Total Area

Combine the areas: $A_{\text{total}} = A_{\text{parallelogram}} + A_{\text{added triangles}} - A_{\text{subtracted triangle}}.$ Substituting the values: $A_{\text{total}} = 45 + 40 - 22.5 = 62.5 \, \text{m}^2.$

Final Answer:

The area of the figure is: $\boxed{62.5 \, \text{m}^2}.$
