Answer:
6
Explanation:
The parallelograms all form a bigger parallelogram with the dimensions of 8 x 9
So to find the inner one you simply subtract the bases of the blues from the total for the base of the inner: 8 - 6 = 2
Then to find the height of the inner on you subtract the height of the red from the height of the blue: 6 - 3 = 3
Then you put these into the equation for area of a parallelogram which is b x h to get 3 x 2, which is equal to 6
Hope this helps!
