In forming the Koch snowflake in Fig., the perimeter becomes greater at each step in the process.

Question:

In forming the Koch snowflake in Fig., the perimeter becomes greater at each step in the process. If each side of the original triangle is 1 unit, a general formula for the perimeter, L, of the snowflake at any step, n, may be determined by the formula

L = 3(4/3)n-1

For example, at the first step when n = 1, the perimeter is 3 units, which can be verified by the formula as follows:

L = 3(4/3)1-1 = 3(4/3)0 = 3 · 1 = 3

At the second step, when n = 2, we determine the perimeter as follows:

L = 3(4/3)2-1 = 3(4/3) = 4

Thus, at the second step the perimeter of the snowflake is 4 units.
