The area of one room is 17.6 m2, which is 5.9 m2 less than the area of the second room, find the total area.

1) Let’s find out what area the second room occupies, if we know that it is 5.9 m² more than the area of the first room, and the area of the first room is 17.6 m².
17.6 + 5.9 = 23.5 m².
2) Let’s find the total area of two rooms, if we know that the area of the first room is 17.6 m², and the area of the second room is 23.5 m².
23.5 + 17.6 = 41.1 m².
Answer: the area of two rooms was 41.1 m².
