If the length of a side of an equilateral triangle is 6 cm, then its height is:
1. \(3\sqrt{3} \ cm\)
2. \(9\sqrt{3} \ cm\)
3. 3 cm
4. \(5\sqrt{3} \ cm\)
1. \(3\sqrt{3} \ cm\)
2. \(9\sqrt{3} \ cm\)
3. 3 cm
4. \(5\sqrt{3} \ cm\)
Correct Answer – Option 1 : \(3\sqrt{3} \ cm\)
Given:
Length of a side of an equilateral triangle = 6 cm
Formula used:
Height (h) = (a × √3)/2
Calculation:
Height = (6 × √3)/2
\(\therefore Height= 3\sqrt{3} \ cm\)
