Question

The altitude of an equilateral trangle is √3 cm. what is its perimeter ?​

Answer 1

Hey MATE!!

Let us assume one side of triangle to be x.

Therefore, applying Pythagoras theorem in right angled triangle formed we get:

x^2 + (x/2)^2 = (√3)^2

=> x^2 + x^2/4 = 3

=> 5x^2 = 12

x = √12/5

x = 2√3/5 Answer
