Let the sides of the equilateral triangle be 'a'.

Area of an equilateral triangle =  \frac{ \sqrt{3} }{4} a^{2}
 
                                \frac{ \sqrt{3} }{4}  a^{2} = 16 \sqrt{3}
                              
                               cancelling  \sqrt{3} on both sides 
 
                                a^{2} = 16 X 4
 
                               [tex]a^{2} = 64 [/tex]
                                 
                                      a = 8 .
 
    perimeter of an equilateral triangle = 3a.
 
                                                            = 3(8)=24.
