======================================================

Step-by-step explanation:

The triangle on the left has a = 8 as one of the legs, and c = 17 as the hypotenuse. Use the pythagorean theorem to find the missing side.

$a^2+b^2 = c^2\\\\8^2+b^2 = 17^2\\\\64 + b^2 = 289\\\\b^2 = 289-64\\\\b^2 = 225\\\\b = √(225)\\\\b = 15\\\\$

This is the height of the parallelogram as marked by the dashed line.

The base is 9 units across the bottom. We won't use 8 as the base because it's too short along the top.

area = base*height

area = 9*15

area = 135 square units
