I have few ideas, but I don't know what you should know. Were you given some sort of formula for area of regular polygon?

Hmm ok, I'm going to use angles. This is probably going to confuse you, but we go with it anyway...|dw:1430245601550:dw|

So if you split regular hexagon into 6 equal piece like this:|dw:1430245704428:dw|

Then those 6 pieces are all equilateral triangle, right? Because all angles are 60 degree.

Now focus on one equilateral triangle. We know that height is 9 in. |dw:1430245916513:dw|

On 30 60 90 triangle we have height of 9 in, so what should that "?" be? Do you know?
