Answer 2

Calculation of the Number of Rooms and their Area

To calculate the number of rooms and their area after merging, we can use the given information.

- There are 20 identical rooms, each with an area of 10 square meters. - During the renovation, 5 rooms were merged together.

To find the number of rooms after merging, we can divide the total number of rooms by the number of rooms merged together:

Number of rooms after merging = Total number of rooms / Number of rooms merged together

Number of rooms after merging = 20 / 5 = 4 rooms.

To find the area of each room after merging, we can divide the total area of the rooms by the number of rooms after merging:

Area of each room after merging = Total area of rooms / Number of rooms after merging

Area of each room after merging = (20 rooms * 10 square meters) / 4 rooms = 50 square meters.

Therefore, after merging 5 rooms together, there will be 4 rooms, and each room will have an area of 50 square meters.
