Question

how many tiles measuring 20 CM x 30 cm each will be required to pave of 1.5 m wide Footpath around a grassy plot of 25 m multiplied 60m​

Answer 1

lenght of tile=20cm

=20/100=0.2m

breadth of tile=30cm

=30/100=0.3m

Area of one tile=0.2*0.3

=0.06m^2

Area of garden=25*60

=1500m^2

No' of tiles = Area of garden /Area of tile

=1500/0.06

=1500*100/6

=25000 tiles
