Question

What is the area of the polygon?

A.
134 cm2

B.
170 cm2

C.
202 cm2

D.
238 cm2

Answer 1

We have to calculate the area of the polygon. This polygon is made of a parallelogram and the right triangle. The area of the triangle: A 1 = a * b / 2 = 8 * 17 / 2 = 136 / 2 = 68 cm^2. The area of a parallelogram : A 2 = a * h = 17 * 6 = 102 cm^2. Finally: A ( polygon ) = A 1 + A 2 = 68 + 102 = 170. Answer: B. 170 cm^2.
