To find the area of a triangle, you can use the formula:
\[ \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \]
In this case, it appears you have a triangle with a base of 4 inches and a height of 8 inches. Using the formula:
\[ \text{Area} = \frac{1}{2} \times 4 , \text{in} \times 8 , \text{in} \]
Calculating that:
\[ \text{Area} = \frac{1}{2} \times 4 \times 8 = \frac{1}{2} \times 32 = 16 , \text{in}^2 \]
Therefore, the area of the triangle is:
\[ \text{Area} = 16 , \text{in}^2 \]
