Question

Find the length of the attitude of an equilateral triangle with side 6 cm ​

Answer 1

Answer:

20.784 cm²

Step-by-step explanation:

Altitude = Height = 6 cm Let length of side be 'a'

So , √3/2 a = 6 So a = 12/√3 So a = 4√3 cm  

This 'a' is the length of the side  

Now, area = (√3/4) × a² So, Area = (√3/4) × (4√3)² So, Area = (√3/4) × (16×3) So, Area = ✓3 × 4 × 3 So, Area = 12√3 So, Area = 12×1.732  

So, Area = 20.784 cm²
