The Koch snowflake is formed as follows. Begin with an equilateral triangle, which we'll assume has sides of length 9. On each side, replace the middle third with two sides of an equilateral triangle having sides of length 3. Then on each of these 12 sides replace the middle third with two sides of an equilateral triangle having sides of length 1. The Koch snowflake is the result of continuing this process indefinitely. The first four stages are shown in Figure 6.
(a) Find the perimeter of the Koch snowflake or show that it is infinite.
(b) Find the area of the Koch snowflake or show that it is infinite?
