To find the area of the polygon, we need to divide it into smaller shapes and add up their areas.
First, we can divide it into a rectangle and a triangle. The rectangle has a height of 5 (the same as the perpendicular side) and a base of 10, so its area is:
5 x 10 = 50
The triangle is half of a rectangle, so its area is:
(1/2) x 5 x 8 = 20
Adding these two areas together, we get:
50 + 20 = 70
Therefore, the area of the polygon is 70 square units.
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.
