The perimeter of this rectangle is 7+3+7+3 = 20. Example: The perimeter of this regular pentagon is 3+3+3+3+3 = 53 = 15. The perimeter of a circle is called the circumference: Circumference = 2pi*radius. Test Case 1 Input (stdin) 10 15 Expected Output 150 50 Test Case 2 Input (stdin) 100 150 Expected Output 15000 500
