Question

A floor 10m long and 7 m broad is to be paved with square tiles of side 0.5m .find number of tiles required

Answer 1

Area of floor= 10*7= 70 sq. m

Area of tile= 0.5*0.5 = 0.25 sq. m

Number of tiles= 70/0.25
= 280 tiles

Answer 2

hii!!

here's ur answer...

given the side of tile is 0.5m.

area of the tile = side²

=0.5×0.5

=0.25m²

length of the floor is 10m and breadth is 7m

area of the floor=l×b

=10×7

=70m²

no. of tiles required to pave the floor=70/0.25

=280

hence 280 tiles are required to pave the floor.

hope this helps..!
