Question

In an equilateral triangle of side 3 root 3 cm, find the lenght of the altitude.

Answer 1

Side of equilateral triangle = 3√3
Altitude of equilateral triangle = \frac{\sqrt{3}}2 a
= \frac{\sqrt{3}}2 × 3√3
= (√3 × 3√3)/2
= 3(√3)²/2
= 3(3)/2
= 9/2
= 4.5

∴altitude of the equilateral triangle is 4.5
Hope this helps you !!

Answer 2

The length of the altitude is 4.5
