Hii....☺

Here is your solution.....✴✴✴✴

_____________________________

Perimeter of an equilateral triangle = 3 × side
=> 12√3 = 3 × Side
=> side = 12√3 ÷ 3
=> side = 4√3 unit.

✴ Side of the equilateral triangle = 4√3

⭐ Area of equilateral triangle = √3/4 × side ^2

=> √3/4 × 4√3 × 4√3
=> 12√3 sq. unit
