Question

The side length of an equilateral triangle is 6 cm. What is the height of the triangle?

Answer 1

formula is

$h = \frac{ \sqrt{3} }{2} \times a$

substitute a=6 you get the answer i.e. h=3√3cm

Answer 2

The height of the triangle is $3\sqrt3\ cm$.

Step-by-step explanation:

Given : The side length of an equilateral triangle is 6 cm.

To find : What is the height of the triangle ?

Solution :

The height of the equilateral triangle is  $h=\frac{\sqrt3}{2}a$.

The side  length of an equilateral triangle is a=6 cm.

Substitute the value,

$h=\frac{\sqrt3}{2}\times 6$

$h=\sqrt3\times 3$

$h=3\sqrt3\ cm$

Therefore, the height of the triangle is $3\sqrt3\ cm$.
