Xiao Ming s living room is 4 5 meters long and 2 8 meters wide, with square floor tiles with a side

The living room area = 5*4

20 square meters;

Use 2 decimeters (i.e. square floor tiles with a side length of 20 cm =, that is, the area of each floor tile is square meters.

The number of floor tiles required for laying floor tiles in the living room = 20

500 pieces. The living room covers an area of 20 square meters, and the floor tiles of this specification are small to affect the appearance, so it is recommended to change to 50*50cm square floor tiles.

= 1260 square decimeters.

5 45 = 1125 square decimeters 1260 square decimeters, so it is not enough.

The area of the living room is square meters.

The area of a fast floor tile is 5 * 5 = 25 square decimeters = square meters of blocks).

So, not enough, poor block.

Surface area = square meters;

The area of 45 blocks = 45 square meters;

So preparing 45 pieces is not enough.

Good luck with your studies.

block) in addition the long side is a multiple.

Width is not a multiple, to be beautiful should be calculated according to 3 meters, need 54 or 45 pieces of color bricks to make up.

Xiao Ming's living room is long and wide, with square floor tiles with a side length of 5 decimeters, is it enough to prepare 45 pieces?

Solution: The living room area is: square meters.

The total area of bricks used is: square meters.

So 45 floor tiles is not enough

Floor tiles are used to lay floors, then calculated according to the equal area, the area of the floor is square meters, and the area of a floor tile is square meters, so the number of bricks needed is a block, and the floor tiles are only sold as an integer, so 51 floor tiles are needed, and 45 are less than 51, so 45 is not enough.
