一直想弄清楚如何完成此操作，但无济于事

Each item in this list is a pair of numbers that represent the dimensions of rooms in a house:

h = [ [18,12], [14,11], [8,10], [8,10] ]

Write a function named area that computes the total area of all rooms, for example:

> area(h)
530

Answer 1

def area(h):
  total_area = 0
  for room in h:
    total_area += room[0] * room[1]
  return total_area
