A r e a o f e a c h t r i a n g l e

= \sqrt{18.6.6.6} = 6.6 \sqrt{3}

T o t a l a r e a o f h e x a g o n

= 6.6.6 \sqrt{3} = 216 \sqrt{3} {cm}^{2}

{it}^{'} s true brother .

The total Area =

6 \times \frac{1}{2} \times 12 \times 12 \times \sin 60 °

= 3 \times 144 \times \frac{1}{2} \sqrt{3} = 216 \sqrt{3}
