A regular hexagon has sides of length 8 cm. Another regular hexagon has sides of length 12 cm. Find the ratio of the area of the larger hexagon to the area of the smaller hexagon.
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).
