The apartment has 3 rooms with a total area of 44.8 m2. One room has an area of 11.3 m

The apartment has 3 rooms with a total area of 44.8 m2. One room has an area of 11.3 m, the other 3.5 m larger. Find the area of the third room.

In order to find out the area of the third room, we first need to know the area of the second. To do this, you need to add 3.5 m to the area of the first room, since the second is larger by a given number of square meters.
11.3 + 3.5 = 14.8 square meters the size of the second room.
Now that we have the dimensions of the second and first rooms, we need to subtract them from the total area so we find out the size of the third room:
44.8 – 14.8 = 30;
30 – 11.3 = 18.7 square meters the size of the third room.
Answer: 18.7 sq.m.
