Answer:
See explanation.
Step-by-step explanation:
To find the area of a parallogram, do A=Bh where a is the area, b is the base, and h is the height.
In this case, b is 9 cm while h is 6 cm. Do A=Bh by multiplying 9 cm by 6 cm. This will give us 54 cm².
The measurement we didn't use is the measure of the diagonal parts of the quadrilateral which, in this case, was 7.5 cm.
