Reasoning and answer: First find the number of rooms per floor in the first wing: 32 rooms / hall * 6 halls / floor = 192 rooms / floor. Then find the total number of rooms in the first wing by multiplying that number by the number of floors: 192 rooms / floor * 9 floors = 1728 rooms. Then find the number of rooms per floor in the second wing: 40 rooms / hall * 9 halls / floor = 360 rooms / floor. Then find the total number of rooms in the second wing by multiplying that number by the number of floors: 360 rooms / floor * 7 floors = 2520 rooms. Then add the total number of rooms in each wing to find the overall total: 1728 rooms + 2520 rooms = 4248 rooms.
The answer: 4248
