Question

a floor measuring 2m by 1.5 m is to be covered with tiles measuring 25 m square. how many tiles will be needed

please write with steps​

Answer 1

2m =200cm

1.5m = 150cm

area of floor=length*breath

=200* 150 cm ^ 2

= 30000 cm ^ 2.

area of tiles =side ^ 2

= (25cm) ^ 2

= 625 cm ^ 2

number of tiles =area of floor/area of one tile

= 30000cm ^ 2/ 625 cm ^ 2

=48
