Solution :
_____________________________________________________________
Given :
The area of equilateral triangle is 64√3 cm².
_____________________________________________________________
To Find :
The perimeter of equilateral triangle ,..
_____________________________________________________________
We know that,
Equilateral triangle has equal sides,.
&
Area of equilateral triangle = sq.units.
Where a is the length of the side of the equilateral triangle,.
So,
We can say that,
⇒
⇒
⇒
⇒
⇒ a² = 256
⇒ a = +16 (a is positive,can't be negative,.As length of equilateral triangle can't be in negative),.
Hence,
We know that, lengths are equal (& tringle has 3 sides),.
⇒ 3a units.
⇒ 3 x 16
⇒ 48 cm,.
