Question

If the area of an equilateral triangle is 16√3 sq units,
then the length of each side of the triangle is
A) 7 units
B) 8 units
C) 9 units
D) 10 units​

Answer 1

Step-by-step explanation:

area of equilateral triangle = √3a²/4

given Area of ∆ = 16√3 sq units

therefore √3a²/4 = 16√3

on cross multiplication we get,

=> 64•√3 = √3•a²

=> a = √64 => 8 units option B
