Count outer edges: 14

Step3: Calculate light green perimeter

Count outer edges: 12

Step4: Calculate dark green perimeter

Count outer edges: 12

Step5: Calculate orange perimeter

Count outer edges: 12

Step6: Calculate other shapes (verify)

Blue: 12, Yellow:12, Pink:10, Light blue:12

Step7: Compare all perimeters

14 (purple) > 12 (others) > 10 (pink)
