Question

Участок пола прямоугольной формы выложили квадратными плитками со стороны 2 дм. всего потребовалось 150 плиток. Найдите длину участка если ширина его 2 метра.

Answer 1

1) 2 х 2 = 4(кв.дм) - площадь одной плитки
2) 4 х 150 = 600(кв.дм) = 6(кв.м) - площадь участка пола
3) 6 : 2 = 3(м) - длина участка пола
Ответ: 3 метра длина участка пола

Answer 2

150/2=75          длина прямоугольной формы

Answer 3

Finding the Length of the Area

To find the length of the rectangular area, we can use the formula:

Area = Length × Width

Given that the width is 2 meters and the area is covered with 150 square tiles, we can calculate the length using the following steps:

1. Calculate the area of one tile in square meters. 2. Divide the total area covered by the tiles by the area of one tile to find the total number of tiles. 3. Use the total number of tiles to find the length of the area.

Let's proceed with the calculations.

Calculations

1. Calculate the Area of One Tile - The side of each square tile is 2 decimeters, which is equal to 0.2 meters. - The area of one tile is calculated as the square of the side length: 0.2 * 0.2 = 0.04 square meters.

2. Find the Total Number of Tiles - Total area covered by the tiles = 150 tiles * 0.04 square meters per tile = 6 square meters.

3. Calculate the Length of the Area - Using the formula: Area = Length × Width - Given width = 2 meters - Length = Total area / Width = 6 square meters / 2 meters = 3 meters.

Conclusion

The length of the rectangular area is 3 meters.
