Question

How many square tiles each other f side 0.5 meter will be required to the floor of a room which is 4 m long and 3 m Broad

Answer 1

The length of the board=4m

The breadth of the board=3m

Area of the board=l×b=4×3=12m^2

Side of square=0.5m

Area of the square=0.5×0.5=0.25m^2

The number of tiles required for flooring is Area of the board÷Area of each square

=>12/0.25=48

Therefore the number of tiles required is 48.

Hope this helped you.

Plz mark me brainiest.

Answer 2

side of square tile=0.5m

x=number of tiles

length=4m

breadth=3m

(0.5×0.5)x=4×3

0.25x=12

x=12/0.25

x=12×100/25

x=12×4

x=48

ans -48 tiles will be needed to cover the room
