Question 60

If ΔABC is an equilateral triangle of side 16 cm, then the length of altitude is

Solution

Side of equilateral triangle = $$a$$ = 16 cm

In an equilateral triangle, median and altitude coincide each other.

Thus, median = altitude = $$\frac{\sqrt{3}}{2}a$$

= $$\frac{\sqrt{3}}{2} \times 16=8\sqrt{3}$$ cm

=> Ans - (C)
