Question

Side of a regular hexagon is 12 cm. Find its area.​

Answer 1

$\text{Area of regular hexagon of side a = } \frac{3 \sqrt{3}}{2}\ a^2\\ \\ \text{Given that side = 12 cm}\\ \\ \text{Area = }\frac{3 \sqrt{3}}{2}\ \times 12^2 = 216 \sqrt{3}\ cm^2 \\ \\ \bold{ \text {Area of regular hexagon is } 216 \sqrt{3}}\ cm^2.$

Answer 2

$Regular \: Hexagon = \frac{3 \sqrt{3} }{2} {a}^{2}$

$Regular \: Hexagon = \frac{3 \sqrt{3} }{2} \times {12}^{2}$

$Regular \: Hexagon = \frac{3 \sqrt{3} }{2} \times 144$

$= 216 \sqrt{3} \: {cm}^{2}$

$Regular \: Hexagon = 216 \sqrt{3} \: {cm}^{2}$
