Question

If the area of an equilateral triangle is 16 root 3 cm ^2 , Then it's perimeter is
a)48 cm
b)24 cm
c)12 cm
d)306 cm​

Answer 1

Answer:

(b) 24 cm

Step-by-step explanation:

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

∴ (side)²√3/4 = 16√3

∴ (side)² = 16x4

∴ (side)² = 64

∴ side = 8 cm

Perimeter of Equilateral Triangle = 3xSide

∴ P = 8cm x 3

∴ P = 24 cm
