Perimeter of an Equilateral Triangle

To find the perimeter of an equilateral triangle, we need to know the length of one side of the triangle. In this case, the length of each side is given as 9 cm.

The perimeter of an equilateral triangle is calculated by multiplying the length of one side by 3, since all sides of an equilateral triangle are equal.

Therefore, the perimeter of a triangle with a side length of 9 cm is:

Perimeter = 9 cm * 3 = 27 cm.
