Question

В коридоре длина которого 5 метров и ширина 2 метра,пол выложили квадратными плитками.Сколько плиток потребовалось,если площадь одной плитки 1 дм в квадрате

Answer 1

1) 5 м * 2 м = 10 кв.м. = 1000 кв.дм - площадь коридора
2) 1000 кв.дм : 1 кв.дм = 1000 плиток

Answer 2

Calculating the Number of Tiles Needed

To calculate the number of tiles needed to cover the floor in the corridor, we can follow these steps:

1. Calculate the Area of the Floor: - The area of the floor can be calculated by multiplying the length and width of the corridor.

2. Convert the Area to Square Decimeters: - Since the area of one tile is given in square decimeters, we need to ensure that the area of the floor is also in square decimeters for a direct comparison.

3. Divide the Area by the Area of One Tile: - Dividing the total area of the floor by the area of one tile will give us the number of tiles needed to cover the entire floor.

Let's proceed with the calculations.

Calculation Steps

1. Calculate the Area of the Floor: - Length of the corridor = 5 meters - Width of the corridor = 2 meters - Area of the floor = Length × Width

The area of the floor is 5 meters × 2 meters = 10 square meters.

2. Convert the Area to Square Decimeters: - 1 square meter = 10000 square decimeters - Therefore, the area of the floor in square decimeters = 10 square meters × 10000 = 100000 square decimeters.

3. Divide the Area by the Area of One Tile: - Area of one tile = 1 square decimeter - Number of tiles needed = Area of the floor / Area of one tile

Number of tiles needed = 100000 square decimeters / 1 square decimeter = 100000 tiles.

Conclusion

To cover the entire floor in the corridor, 100,000 tiles will be needed, given that the area of one tile is 1 square decimeter.
