# The area of an equilateral triangle is $$\Large \Large 4\sqrt{3}$$sq cm. Find the length of each side of the triangle

 A) 3 cm B) $$\Large 2\sqrt{2}$$cm C) $$\Large 2\sqrt{3}$$cm D) 4 cm

 D) 4 cm

Area of equilateral triangle = $$\Large \frac{\sqrt{3}}{4}a^{2}$$

=> $$\Large 4\sqrt{3}=\frac{\sqrt{3}}{4}a^{2}$$ => $$\Large a^{2}$$=16

a=$$\Large \sqrt{16}$$=4cm
