Use the image to answer the question.

A pentagon is formed of two perpendicular lines on a base, which converge to form a triangular end. The pentagon points downward and has a total height of 8. The base measures 10 and the perpendicular side measures 5.

Find the area of the polygon in square units.

square units

The area of a pentagon is given by the formula: \( \text{{area}} = \frac{1}{2} \times \text{{base}} \times \text{{height}} \)

In this case, the base is 10 and the height is 8. Substituting in these values, we get:
\( \text{{area}} = \frac{1}{2} \times 10 \times 8 = 40 \) square units.

Therefore, the area of the pentagon is 40 square units.
