To find the area of the triangle shown in the image, we can use the formula for the area of a triangle:

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

From the image:
- The base of the triangle is 18 mm.
- The height of the triangle is 16 mm.

Now, applying the values:

\[
\text{Area} = \frac{1}{2} \times 18 \, \text{mm} \times 16 \, \text{mm}
\]

\[
\text{Area} = \frac{1}{2} \times 288 \, \text{mm}^2
\]

\[
\text{Area} = 144 \, \text{mm}^2
\]

So, the area of the triangle is **144 square millimeters**.
