Answer 2

Calculating the Eighth Apartment's Living Area

To calculate the living area of the eighth apartment, we can use the information provided about the living areas of the other apartments and the average living area per apartment.

Given: - 2 apartments have a living area of 22.8 m² each. - 3 apartments have a living area of 16.2 m² each. - 2 apartments have a living area of 34 m² each. - The average living area per apartment is 24.7 m².

Let's calculate the living area of the eighth apartment.

Calculation

We can start by calculating the total living area of the known apartments and then use the average living area per apartment to find the living area of the eighth apartment.

Total living area of known apartments: - (2 * 22.8) + (3 * 16.2) + (2 * 34) = 45.6 + 48.6 + 68 = 162.2 m²

Average living area per apartment: - 24.7 m²

Living area of the eighth apartment: - Total living area - (Total number of apartments - 1) * Average living area per apartment - 162.2 - (7 - 1) * 24.7 - 162.2 - 6 * 24.7 - 162.2 - 148.2 - 14 m²

So, the eighth apartment has a living area of 14 m².

Conclusion

The eighth apartment on this floor has a living area of 14 m², based on the given living areas of the other apartments and the average living area per apartment.
