Question

 If the area of an equilateral triangle is 36√3square centimeter, then its perimeter is -------------​

Answer 1

Answer:

Area of Equilateral Triangle = √3/4 × (side)²

36√3 = √3/4 × (a)²

36√3 × 4/√3 = a²

a² = 36 × 4

a = √36 × √4

a = 6 × 2

a = 12 cm

Perimeter of Equilateral Triangle = 3 × side

= 3 × a

= 3 × 12

= 36 cm

Answer 2

Answer:

Area of eqartorial triangle =√4/3 (side × side)

=√4/3(side×side) =36√3

(side×side) = 36×4 = 9×4×4 =(=(4×3) 2

side =12cm

perimeter = 3×12=36
