Answer:
264 cm^2.
Step-by-step explanation:
The area = 1/2 * height * sum of the parallel sides
= 1/2 * 12 * (28 + 16)
= 6 * 44
= 264 cm^2.
Andrew answered 34 questions correctly.
I got the answer by divided the 85% by 100% (100% because it's the total percentage.) I received 0.85 when dividing that. Then, I took the 0.85 and divided it by the total of 40 questions, and that gave me the answer of 34.
