# Write a Python program to round every number of a given list of numbers and print the total sum multiplied by the length of the list.  
 nums = [22.4, 4.0, -16.22, -9.10, 11.00, -12.22, 14.20, -5.20, 17.50]
print("Original list: ", nums)
print("Result:")
lenght=len(nums)
print(sum(list(map(round,nums))* lenght))
