Question

The height of an equilateral triangle is 4√3. What is the perimeter of the equilateral triangle?
a) 12 units
b) 12√3 units
c) 24 units
d) 24√3 units

Answer 1

Height of an equilateral triangle = $\sqrt{3}$ / 2 × a

where, a is the length of each side

$\sqrt{3}$ / 2 × a = 4  $\sqrt{3}$

a = 8

therefore, perimeter = 3×a = 3×8 = 24 units
