720

Step-by-step explanation:

When you multiply 12 by 6, you get 72, and in this case, it will end up being 720 to correspond with the way it is set up.

A hexagon is six equilateral triangles, so 12 30/60/90 triangles.

Each one has base half of the 6cm, so 3 cm.  There's an altitude of 3√3.

So twelve triangles has an area of 12(1/2)3(3√3) = 54√3 ≈ 93.5

D. 93.5 cm
