To calculate the area of the triangle, the formula is:

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

From the image:

• The base of the triangle is $4$ units.
• The height of the triangle is $10$ units.

Substituting these values into the formula:

$\text{Area} = \frac{1}{2} \times 4 \times 10 = 20 \, \text{units}^2$

Final Answer:

The area of the triangle is 20 units².
