Question

The area of an equilateral triangle is $4\sqrt{3}cm^2$ . The length of each side of the triangle is :

• A. 3 cm
• B. $$2\sqrt{2}cm$$
• C. $$9\sqrt{3}cm$$
• D. 4cm

Answer 1

Answer:

D. 4cm

Area of the equilateral triangle $=\frac{\sqrt{3}}{4}\times{(side)^2}=4\sqrt{3}$

$4\sqrt{3}=\frac{\sqrt{3}}{4}\times{(side)^2}$

$(side)^2=16$

$side=4 cm$
