Answer 2

Answer:

$\boxed{\red{Perimeter = 36 cm }}$

Step-by-step explanation:

$\huge \text{Given}$

$\red\bigstar$ Area of an Equilateral Triangle  = 36√3cm²

$\huge \text{To Find}$

$\red\bigstar$ The Perimeter of the Triangle.

$\huge \text{Answer}$

Area of an equilateral triangle = √3/4 a² ( a is the side of the Equilateral Triangle)

√3/4 a² =  36√3

a² = 36 x 4x 1

a² = 36 x 4

a² = 144

a = $\sqrt{144}$

a = 12 cm

$\red\bigstar$ We Know that Perimeter of an Equilateral Triangle = 3 x side

$\red\bigstar$ Here, Perimeter = 3 x 12 = 36 cm.
