To calculate the total area of the vegetable garden from the given image, we can break the shape into a rectangle and a triangle, and then sum their areas.

1. Rectangle:

   • Length (L) = 18 m
   • Width (B) = 6 m
   • Area of rectangle = $L \times B = 18 \, \text{m} \times 6 \, \text{m} = 108 \, \text{m}^2$

2. Triangle:

   • Base (b) = 6 m
   • Height (h) = 5 m
   • Area of triangle = $\frac{1}{2} \times b \times h = \frac{1}{2} \times 6 \, \text{m} \times 5 \, \text{m} = 15 \, \text{m}^2$

3. Total Area:

   • Total area of the vegetable garden = Area of rectangle + Area of triangle
   • Total area = $108 \, \text{m}^2 + 15 \, \text{m}^2 = 123 \, \text{m}^2$

So, the total area of the vegetable garden is $123 \, \text{m}^2$.
