The area of an equilateral triangle is numerically equal to its perimeter. Find its perimeter correct to 2 decimal places. (hint: area of an equilateral triangle is
[tex] \frac{ \sqrt{3} }{4} \times {(side)}^{2} [/tex]
and its perimeter is 3×side.....
please help me....

hope it helps u :)
Perimeter of ∆ = 3a
= 3×6.92
= 20.76
OR we can say
Perimeter of ∆ = 3a
= 3×4√3
= 12√3
