Question

Папа решил выложить пол на кухне квадратами из пластика. Длина кухни 4 м, а ширина 3 м. Сколько потребуется пластиковых квадратов, если сторона такого квадрата 2 дм? Помни! 1м(в квадрате) = 100 дм(в квадрате)

Answer 1

2х2=4дм²

3х4=12м²=1200дм²

1200:4=300(шт)-пластиковых квадратов потребуется

Answer 2

Calculating the Number of Plastic Squares Needed for the Kitchen Floor

To calculate the number of plastic squares needed for the kitchen floor, we can follow these steps:

1. Convert the dimensions of the kitchen from meters to decimeters: - The length of the kitchen is 4 meters, which is equivalent to 400 decimeters. - The width of the kitchen is 3 meters, which is equivalent to 300 decimeters.

2. Calculate the area of the kitchen: - The area of the kitchen can be calculated by multiplying the length and width together. - Area = Length x Width - Area = 400 dm x 300 dm - Area = 120,000 square decimeters

3. Determine the area of each plastic square: - The area of each plastic square is calculated by squaring the length of one side. - Given that the side of each plastic square is 2 decimeters, the area of each square is 2 dm x 2 dm = 4 square decimeters.

4. Calculate the number of plastic squares needed: - To find the number of plastic squares needed, divide the total area of the kitchen by the area of each plastic square. - Number of squares = Total area / Area of each square - Number of squares = 120,000 square decimeters / 4 square decimeters - Number of squares = 30,000

Answer:

If the side of each plastic square is 2 decimeters, then 30,000 plastic squares will be needed to cover the kitchen floor.

This calculation is based on the dimensions provided and the size of the plastic squares.
