To find the area of the triangle using the formula \( A = \frac{1}{2}bh \), where \( b \) is the base (width) and \( h \) is the height:
- Base \( b = 8 , m \)
- Height \( h = 3 , m \)
Now, substitute the values into the formula:
\[ A = \frac{1}{2} \times 8 \times 3 \]
Calculating this:
\[ A = \frac{1}{2} \times 24 \] \[ A = 12 \]
Thus, the area of the triangle is:
12 m²
