* Perimeter: The total distance around the outside of a shape.

* Hexagon: A six-sided shape.

Calculation:

* Since all sides are equal, we multiply the length of one side by the number of sides:

* Perimeter = Side Length x Number of Sides

* Perimeter = 12 centimeters x 6

* Perimeter = 72 centimeters

Therefore, the perimeter of the hexagon is 72 centimeters.
