Answer 1

Answer:

$Area \: of \: the \: equilateral \: triangle = \frac{ \sqrt{3} }{4} \times {(side)}^{2} \\ \frac{ \sqrt{3} }{4} \times {x}^{2} = 36 \sqrt{3} \\ {x}^{2} = 36 \times 4 \\ x = 6 \times 2 \\ x = 12 \\Therefore, \: side \: of \: the \: equilateral \: triangle = 12 \: cm\\ Hence, \: perimeter \: of \: the \: equilateral \: triangle \: is = 3 \times (side) \\ 3 \times 12 = 36 \: cm$

36 cm is the right answer.
