(a) 8 cm
(b) 16 cm
(c) 24 cm
(d) 32 cm

Plz tell me the correct answer... ​

Answer 1

Answer:

Given, area of an equilateral triangle = 16√3 cm2

Area of an equilateral triangle = √3/4 (side)2

√3/4(Side)2 = 16√3 ⇒ (Side)2 = 64

⇒ Side =8 cm

[taking positive square root because side is always positive]

Perimeter of an equilateral triangle = 3 x Side= 3 x 8 = 24 cm

Hence, the perimeter of an equilateral triangle is 24 cm.
