A) \[4\sqrt{3}\]
B) \[\frac{2}{\sqrt{3}}\]
C) \[2\sqrt{3}\]
D) \[\frac{4}{\sqrt{3}}\]
Correct Answer: C
Solution :
\[\angle B=\frac{\pi }{3},\] by sine Rule \[\sin \,A=\frac{1}{2}\] \[\Rightarrow A={{30}^{o}},a=2,b=2\sqrt{3},c=4\] \[\Delta =\frac{1}{2}\times 2\sqrt{3}\times 2=2\sqrt{3}sq.\,cm\]You need to login to perform this action.
