Question

В зале длиной 15 м и шириной 8 м надо покрыть пол квадратными плитками сколько потребуется плиток если площадь каждой плитки шесть квадратных дециметров. Пожалуйста помогите решить эту задачу спасибо всем кто ответил На мой вопрос

Answer 1

$15m=15\cdot10=150dm$
$8m=8\cdot10=80dm$
$S_z=150\cdot80=12000dm$
$\frac{12000}{6}=2000$ плиток

Answer 2

6дм²= 0,06м²- площадь одной плиточки
15м•8м=120м²-площадь комнаты
120м²:0,06м²=2000 плиток потребуется.
ответ: 2000 плиток

Answer 3

Problem Analysis

To find out how many tiles are needed to cover the floor of a room, we need to calculate the area of the room and then divide it by the area of each tile.

Calculation

The room is 15 meters long and 8 meters wide, so the area of the room can be calculated as follows:

Area of the room = length × width

Area of the room = 15 m × 8 m

To convert the area to square decimeters, we need to multiply it by 100 to account for the conversion from meters to decimeters:

Area of the room in square decimeters = (15 m × 8 m) × 100

Now, we can calculate the number of tiles needed by dividing the area of the room by the area of each tile. Each tile has an area of 6 square decimeters:

Number of tiles needed = (Area of the room in square decimeters) / (Area of each tile)

Calculation Result

Let's calculate the number of tiles needed:

Area of the room = 15 m × 8 m = 120 square meters

Area of the room in square decimeters = (15 m × 8 m) × 100 = 12000 square decimeters

Number of tiles needed = 12000 square decimeters / 6 square decimeters = 2000 tiles

Therefore, you will need 2000 tiles to cover the floor of the room.

Answer

To cover the floor of a room that is 15 meters long and 8 meters wide with square tiles, you will need 2000 tiles if each tile has an area of six square decimeters.
