Answer:
1/9
Step-by-step explanation:
You find the area of the rectangle first (1/2 by 1/3)
then find the area excluding the parallelogram (the two triangles outside, which would be 1/6 by 1/3 since both are of the same side measurement)
(sorry if this is hard for you to understand by the way)
Then subtract the answer from step 2 from step 1 and voila, you get your answer
The first one
