I have an exam coming up, and one of the types of question I will need to know is how to compute the area of Kock's snowflake. I'm not entirely sure how to do it. I know we use infinite series with it, but I don't really understand how to do it. Any help is appreciated.

The example question we have on our syllabus is as follows: Computing thearea of Koch's Snowflake with a starting perimeter of 81 (the answer is 1166.4, but show why)
