Question

how many tiles of area 15cm sq will be needed to cover a floor 5.85m by 6.90 m

Answer 1

no of tiles=area of floor/area of the tile
area of rectangular floor=l×b
l in cm =585 cm
b in cm =690 cm
=558×690
=385020cm²

no of tiles=385020/15
=25668 tiles

Answer 2

Answer:

26910

Step-by-step explanation:

1m = 100 cm

5.85 m = 585 cm

6.9 m = 690 cm

total Area = 585*690  cm^2

area of 1 tile = 15 cm^2

no of tiles required = 585*690/15

=  585*46

=  26910
