Hi Mate!!
Equilateral trangle:-
1) All sides and all angles are equal ( 60° each )
2) Area of equilateral is a² √3 / 4
3) perimeter of equilateral triangle = 3a
Exp:-
Let it's side be = a
a² √3 / 4 = 4√3
=>. a² = 16
=>. a = 4 or a = -4
a = -4 will be rejected bcoz length can't be -ive
So, it's perimeter is = 3 ( 4unit ) = 12uint.
