Answer 2

Hi

Here is ur answer

=====================================================

Answer:

Perimeter = 36 cm

Step-by-step explanation:

Area = 36√3 cm

Area of equilateral triangle = √3 / 4 a²

 36√3 =   √3 / 4 a²

√3 will get cancelled out,

36 × 4 = a²

144 = a²

Therefore,

a = √144

a = 12 cm

Perimeter = 3a

                = 3 × 12

                = 36 cm
