Question

Square tiles of side 15 cm are used to cover the floor of a bathroom of length 3 m and breadth
2 m. How many such files have to be bought? Of number of tiles comes in decimals round it of
to next higher number because practically you cannot buy less number of tiles than required)​

Answer 1

Step-by-step explanation:

First,

We have to find the area of the floor of the bathroom

given,

length=3m

breadth=2m

Area=l×b

= 3m×2m

= 6m^2

Second step,

Side of each square tile= 15cm

Area of each square tile= side×side

=15cm×15cm

=225cm^2

Now, lastly

No. of tiles to be brought= area of the bathroom ÷

area of each tile

=6m^2÷225cm^2

=60000cm^2÷225cm^2

After cancelletion we will get in decimal 266.6 tiles

Therefore we can say that no. of tiles required is 267 tiles by rounding off.
