In order to lay floor tiles for a square space in a residential area, it was originally planned to use square floor tiles with a side length of 2 decimeters, which required 2500 tiles. Later, it was changed to square floor tiles with a side length of 4 decimeters. How many such tiles do you need? (this is the question)
The square area is 2 times 2 times 2500, which is 10000 square decimeters
The area of the later revolution is 4 times 4 = 16 square decimeters
10000 divided by 16 = 625
So we need 625 of them
Xiaomin's house is going to lay 4-decimeter-long square tiles on the floor of bedroom A. how many tiles do you need to buy? If each tile costs 5 yuan, how much do you need at least?
The actual area of bedroom a is 20.52cm;
The actual area of a bedroom can't be only 20.52cm, but it can be 20.52m in real life;
According to this calculation,
What is the area of a tile
4 decimeters = 0.4 meters
S = a * a = 0.4 * 0.4 = 0.16 (M2)
Number of tiles required
20.52 / 0.16 = 128.25 (piece)
Add one to 129
5 yuan per tile, so
Total price = unit price * quantity = 5 * 129 = 645 yuan
A bedroom is 48 decimeters long and 42 decimeters wide. Now it is paved with square tiles. How many decimeters is the maximum side length of square tiles more appropriate
Six decimeters
The floor of Xiaohong's room is 40 decimeters long and 32 decimeters wide. If the floor is covered with square tiles, the side length of the tiles is required to be an integer. What is the maximum side length of the tiles
The problem is actually to find the greatest common factor of 40 and 32,
（40,32）=8
The maximum side length of floor tile is 8 decimeters
How many tiles does it take to lay a room floor with a side length of 2 decimeters and a side length of 4 decimeters

Give a rectangular room floor tile, the room is 6 meters long, 4 meters wide, with a side length of 20 cm square floor tile, each brick 5 yuan, spread the whole room with how much money?
Area of the house: 6x4 = 24 square meters = 240000 square centimeters
Area of each tile: 20x20 = 400 square centimeter
Number of tiles required: 240000 / 400 = 600
Amount of money used: 5x600 = 3000 yuan
To a rectangular room paving tiles, the room 6 meters long, 4 meters wide, with 20 cm square tiles paving, each brick 5
House area = 6 * 4 = 24 meter
Ground area = 0.2 * 0.2 = 0.04 meter
Use: 24 / 0.04 = 600 pieces
5 yuan per piece is 600 * 5 yuan = 3000 yuan
