Calculation of the Third Room's Area

To find the area of the third room in a three-bedroom apartment, we can use the information provided about the total area of the apartment and the areas of the other rooms.

Given: - Total area of the three-bedroom apartment: 128 m² - Area of the first room: 23 m² - Area of the second room: 9 m² larger than the first room - Area of the bathroom: 7 m² - Area of the kitchen: 15 m²

To calculate the area of the third room, we need to subtract the areas of the first room, second room, bathroom, and kitchen from the total area of the apartment.

Let's calculate it step by step:

1. Area of the second room: - The second room is 9 m² larger than the first room. - Therefore, the area of the second room is 23 m² + 9 m² = 32 m².

2. Total area of the first and second rooms: - The total area of the first and second rooms is 23 m² + 32 m² = 55 m².

3. Total area of the first and second rooms, bathroom, and kitchen: - The total area of the first and second rooms, bathroom, and kitchen is 55 m² + 7 m² + 15 m² = 77 m².

4. Area of the third room: - To find the area of the third room, we subtract the total area of the first and second rooms, bathroom, and kitchen from the total area of the apartment. - The area of the third room is 128 m² - 77 m² = 51 m².

Therefore, the area of the third room in the three-bedroom apartment is 51 m².
