Answer 1

Let the side be 'a'.

Given that altitude of an equilateral triangle = 8cm.

We know that Altitude of an Equilateral triangle = $\frac{\sqrt{3}}{2} * a$

$=>\frac{\sqrt{3}}{2} * 8$

$=> 4\sqrt{3}cm$

Hope it helps!

Answer 2

Let to be side a Then,


We know that Equilateral∆ Have √3/4

 Again


 NOW PUTTING THE VALUE OF REQUIRED Terms
