Calculate Triangle Area: Using Height 8 and Base 11

To solve for the area of triangle $\triangle ABC$, we will use the standard formula for the area of a triangle:

$\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}$

Given:
Base $BC = 11$
Height $AD = 8$

Substitute these values into the area formula:

$\text{Area} = \frac{1}{2} \times 11 \times 8$

Calculate the area:

$\text{Area} = \frac{1}{2} \times 88 = 44$

Therefore, the area of triangle $\triangle ABC$ is $\boxed{44}$.
