Finding the area of a parallelogram uses the formula base * height. You can see that the base is 20 cm, and that the missing length is 6 cm. The area of the parallelogram is 160 cm², and the triangle (b*h/2), has an area of 37.8 cm². Add these up, and the total area of this shape is 197.8 cm².

The area of the parallelogram is "base times height," so its 20*8 which is 160.
To find the area of the triangle, we have to find the base which incorporates Pythagorean'd theorem. 100 - 64 = 36, sqrt 36 is 6. So the base of the triangle is 6, the height is 12.6, thus the area is 6.3 * 6, which is 37.8
Adding the two values up, we get 37.8 + 160 = 197.8
