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 scenario, the base of the triangle is 8 units and the height is 5 units. Plugging these values into the formula gives:

\[

\text{Area} = \frac{1}{2} \times 8 \times 5

\]

\[

\text{Area} = \frac{1}{2} \times 40

\]

\[

\text{Area} = 20 \text{ square units}

\]

This demonstrates that the calculation aligns with the definition of the area of a triangle, resulting in an area of 20 square units. Understanding the formula and correctly substituting the dimensions of the triangle leads to the right answer. The choices provided include other areas that do not match the calculation based on the standard formula for the area of a triangle.
