Question

18. The dimensions of a floor of a room are 8 m by 6 m. How many square tiles will be required to cover the floor if the side of the tile is 25 cm?​

Answer 1

Step-by-step explanation:

Area of the floor=length×Breadth=(800×600)cm^2

Area of each tile=side× side= (25×25)cm^2

$\tt \longrightarrow \: Number \: of \: tiles \\ \tt \implies \: \frac{ \cancel{800} \times \cancel{600}}{ \cancel{25} \times \cancel{25}} = 32 \times 24 = 768 \: tiles$

Answer 2

Step-by-step explanation:

18. The dimensions of a floor of a room are 8 m by 6 m. How many square tiles will be required to cover the floor if the side of the tile is 25 cm?

Area of floor = 36×24=864 sq. m

Area of one tile = 6×6=36 sq. m.

Therefore,

Tiles required =

36

864

=24 tiles
