A) \( \Large 6\sqrt{3} \)cm |
B) \( \Large 2\sqrt{3} \)cm |
C) \( \Large 5\sqrt{3} \)cm |
D) \( \Large 7\sqrt{3} \)cm |
A) \( \Large 6\sqrt{3} \)cm |
According to the question,
\( \Large \frac{\sqrt{3}}{4}a^{2}= 3\sqrt{3} \)
=> \( \Large \frac{1}{4}a^{2} \)=3 => \( \Large a^{2}=3\times 4 \)
a=\( \Large 2\sqrt{3} \)
Required perimeter=3a=\( \Large 3\times 2\sqrt{3} \)
=\( \Large 6\sqrt{3} \)
