Calculation of the Total Area of the Apartment

To find the total area of the apartment, we need to use the given information about the kitchen and the non-residential areas.

According to the information provided, the kitchen occupies 0.4 (40%) of all non-residential areas in the apartment, and the non-residential areas make up 5/18 of the total area of the apartment.

Let's denote the total area of the apartment as A.

The kitchen area can be calculated as 0.4 times the total area of all non-residential areas: Kitchen area = 0.4 * (5/18) * A

Since the kitchen area is given as 10m², we can set up the equation:

0.4 * (5/18) * A = 10

To find the total area of the apartment, we can solve this equation for A.

Let's calculate it step by step:

1. Multiply 0.4 and 5/18: 0.4 * (5/18) = 0.1111 2. Divide both sides of the equation by 0.1111: A = 10 / 0.1111

Using a calculator, we can find that A ≈ 90.

Therefore, the total area of the apartment is approximately 90 square meters.

Please note that the calculations are based on the given information and assumptions.
