If the numerical value of the perimeter of an equilateral triangle is 3\sqrt{3} times the area of it, then the length of each side of the triangle is

A2 units

B3 units

C4 units

D6 units

Answer:

C. 4 units

Read Explanation:

If the side of the equilateral triangle be x units,

then,

3x=3(34x2)3x=\sqrt{3}(\frac{\sqrt{3}}{4}x^2)

=>3x=\frac{3x^2}{4}

x=4unitsx=4units
