Question

A Koch snowflake begins with an equilateral triangle with side length of 1 (stage 0). Trisect each side and attach a smaller equilateral triangle to the center of each side (stage 1). Repeat for each triangle to obtain stage 2. Find the perimeter of the stage 2 snowflake.

Answer 1

Each triangle will have a side length of 1/3.
Since you do this for the 3 sides, each equilateral triangle has a perimeter of 1, so the 3 triangles will have a total perimeter of the stage 2 snowflake = 3
