Question

# A hall measures 20m by 12m. The number of Square tiles of side 4m required to pave the floor is​

Answer 1

Answer:

15

Step-by-step explanation:

Area of hall= Area of one tile * no. of tiles

20*12 = 4*4*n

no. of tiles= 4*4*3*5/ 4*4

no. of tiles= 3*5 = 15

Answer 2

Answer:

12 tiles

Step-by-step explanation:

Given,

Let the length and breadth of a hall be l and b respectively.

Length of hall (l) = 16 m

Breadth of hall (b) = 12 m

Area of hall = Length × Breadth

Area of hall = 16 m × 12 m

Area of hall = 192 m^2

Here

Area of hall = 192 m^2

Side of one tile = 4 m

Area of one tile = (side of one tile)^2

Area of one tile = ( 4 m )^2

Area of one tile = 16 m^2

Number of tiles required to pave the floor =

\frac{area \: of \: hall}{area \: of \: one \: tile}

areaofonetile

areaofhall

Number of tiles required to pave the floor = 192/16

Number of tiles required to pave the floor = 12 tiles

Hence,

192 m^2 of tiles is required.

And

12 tiles are required to pave the floor of side 4 m of tile.
