To solve the problem of finding the area of the given shape, we can break it into two parts:

1. The rectangle: The rectangle is $15 \, \text{m} \times 8 \, \text{m}$. $\text{Area of the rectangle} = 15 \times 8 = 120 \, \text{m}^2$

2. The triangle: The base of the triangle is $23 - 15 = 8 \, \text{m}$, and its height is $8 \, \text{m}$. $\text{Area of the triangle} = \frac{1}{2} \times \text{base} \times \text{height} = \frac{1}{2} \times 8 \times 8 = 32 \, \text{m}^2$

Finally, adding the areas of the rectangle and the triangle: $\text{Total area} = 120 + 32 = 152 \, \text{m}^2$

Answer:

The area of the shape is 152 m².
