Answer 1

6*5=30(м²)- Sкомнаты 
270:30=9(м²)-S1 плитки
5*4=20(м²)-S2 комнаты
20*9=180(м²)-Sплиток
ответ: 180 плиток

Answer 2

Calculating the Number of Tiles Needed

To calculate the number of tiles needed for the second room, we can use the ratio of the areas of the two rooms.

Given: - Length of the first room = 6m - Width of the first room = 5m - Number of tiles for the first room = 270

We can calculate the area of the first room using the formula: Area = Length × Width.

For the first room: - Area = 6m × 5m = 30 square meters

Now, we can calculate the area of the second room using the same formula.

For the second room: - Length of the second room = 5m - Width of the second room = 4m - Area = 5m × 4m = 20 square meters

To find the number of tiles needed for the second room, we can use the ratio of the areas of the two rooms:

Number of tiles for the second room = (Area of the second room / Area of the first room) × Number of tiles for the first room

Substituting the values: - Number of tiles for the second room = (20 / 30) × 270 - Number of tiles for the second room = (2/3) × 270 - Number of tiles for the second room = 180

So, 180 tiles will be needed for the second room.
