Answer:
[tex]3\sqrt{3}[/tex]
Step-by-step explanation:
We are asked to find the height of an equilateral triangle, whose side length is 6 cm.
We know that all sides of an equilateral triangle are equal.
We can find height of an equilateral triangle using formula [tex]\frac{\sqrt{3}}{2}a[/tex], where 'a' represents side length of equilateral triangle.
[tex]\frac{\sqrt{3}}{2}\cdot 6[/tex]
[tex]\sqrt{3}\cdot 3[/tex]
[tex]3\sqrt{3}[/tex]
Therefore, the height of the equilateral triangle is [tex]3\sqrt{3}[/tex].
