To find area $ A $ use formula:
$$ A = \frac{ a^2 \sqrt{3}}{2} + 3 a l $$After substituting $ a = 2 $ and $ l = 2.7 $ we have:
$$ A = \frac{ 2^2 \sqrt{3}}{2} + 3 \cdot 2 \cdot 2.7 $$$$ A = \frac{ 4 \sqrt{3}}{2} + 3 \cdot 5.4 $$$$ A = \frac{ 4 \sqrt{ 3 }}{2} + 16.2 $$$$ A = 2 \sqrt{ 3 } + 16.2 $$$$ A = 19.6641 $$
