Question

if altitude of equilateral triangle is root 3 cm . find the perimeter of triangle

Answer 1

The all the angle are equal
3multiplty 3
9cube= a3
729

Answer 2

Altitude = √3 cm
We know that altitude bisects base

Let side be a

Then, Altitude² + (a/2)² = a²
       so, √3² = a²-a²/4
    so, 3 = 3a²/4
    so, a² = 4
  so, a = 2 cm

So, Perimeter = 2*3 = 6cm
