Answer:

[tex]19.5[/tex] [tex]cm[/tex]

Step-by-step explanation:

Perimeter is the sum of the length of all sides

Since an equilateral triangle has 3 equal sides we just multiply 6.5 by 3

[tex]6.5*3=19.5[/tex]

I hope this helps
You just multiply 6.5 gm by 3 since each side is equal! This gives you 19.5cm
