Best answer 4 votes 4 votes C) Area of equilateral triangle is given by $\frac{\sqrt{3}}{4}a^2\ =\ \sqrt{3}\\a\ =\ 2\\Perimeter\ =\ 3a\ =\ 6$ Tuhin Dutta answered Feb 21, 2018 edited May 30, 2019 by akash.dinkar12 Tuhin Dutta comment Share Follow See all 0 reply Please log in or register to add a comment.
3 votes 3 votes We know the area of an equilateral Triangle$= \frac{\sqrt3}{4} \ a^2 $ Where 'a' is length of sides of triangle. so by given condition 9 $\frac{\sqrt3}{4} \ a^2 = \sqrt 3$ i.e $a^2 =4 $ so $a=2$ Perimeter$=3*a=3*2=6$ So option (C) is Correct.
