If the area of the equilateral triangle is 8√3 cm^2 , then its perimeter is in cms

Correct option is (C) 12√2 Let side of equilateral triangle is a cm. Then \(\frac{\sqrt3}4a^2=8\sqrt3\) \((\because\) Area of equilateral triangle is \(\frac{\sqrt3}4a^2)\) \(\therefore a^2=32\) \(\Rightarrow a=\sqrt{16\times2}=4\sqrt2\) \(\therefore\) Perimeter of equilateral triangle = 3a \(=3\times4\sqrt2\) \(=12\sqrt2\,cm\)
