How do I evaluate double integral as the limit of a sum: [tex]\int\int[/tex] 1 dA with a snowflake region constructed as follows: Step 1: Start with a square of area 1 unit2. Step 2: Divide each edge into 3 and construct a smaller square on the middle third, thus creating new edges. Step 3: Repeat step 2. I know to use a simple geometric series but not sure how to use it or work put this integral. Please help.
