The area of three rooms is 44 m2, the area of the first room is 24 m2, the area of the second

The area of three rooms is 44 m2, the area of the first room is 24 m2, the area of the second room is 8 m2, which is equal to the area of the third room. solve the problem in two ways.

1) In the first method, we calculate how many square meters are in the third room, subtracting the sum of the areas of the first and second rooms from the total quadrature of three rooms:

44 – (24 + 8) = 12 (m²).

2) In the second method, we first subtract the area of the first room from the total square of the three rooms:

44 – 24 = 20 (m²).

So we got the sum of the areas of the second and third rooms. Let us find the area of the third room by subtracting the area of the second room known by the condition from the result obtained:

20 – 8 = 12 (m²).

Answer: 12 m².
