Question

Arun is 680 m m long and 323 m wide it is to be paved with square marble tiles of side 20 cm how many such tiles will be required

Answer 1

First of all it should be A room

L=680m

B=323m

Area of room= L×B

=680×323 m^2

Side of square marble= Side^2

=(20/100)^2

=400/10000 m^2

=0.04m^2

No. of tiles = Area of room / Area of 1 sq. tile

=(680×323)/0.04

=5491000 tiles
