    The hexagons are similar. Therefore \frac{A_1}{A_2} = \left( \frac{12}{8} \right)^2. (This idea is sure to be in your class notes or textbook).

    1. Ask for notes. Or use some initiative to find some notes.

    2. All parents are biased - some more than others.

    You were shown the approach, advised what to do and given confirmation of the correct answer. I don't see the point of this reply. Even had I not alrady conformed the correct answer, it should be evident that the ratio of something larger to something smaller cannot possibly be 2 : 3 (and the reference to D is pointless since your original post makes no mention of options).
