Question

If are of equilateral triangle
$4 \sqrt{3}$
then find is perimeter

Answer 1

root3 / 4 side^2 = 4 root 3

side = 4

peimeter = 4*3=12cm

Answer 2

Answer

  Perimeter of equilateral  = 12

Explanation  

Step 1: To find the side of equilateral triangle

It is given that,    

If area of equilateral triangle is 4 $\sqrt{3}$

Area of equilateral triangle with side a can be written as

  Area , A =$\frac{\sqrt{3}a^{2}}{4}$  

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

           $a^{2}$= 4 x 4 = 16

             a=4

Step 2: To find the perimeter of equilateral  triangle

    Perimeter of equilateral  = 3a =3 x 4 = 12
