Solution in Python3 (judge verdict: Wrong Answer)

#!usr/bin/env python3

def area_circumference(s):
    return str(int(s[0]) * int(s[2])) + ' ' + str((int(s[0]) + int(s[2])) * 2)

def main():
    print(area_circumference((input('Enter two numbers concatenated by a single space, e.g. \'3 5\': '))))

if __name__ == '__main__':
    main()
