150m=15000cm
9m=900cm
Thus,(15000*900)/(22.5*7.5)
=13500000/168.75
=80000

hello frnd!!!

here's ur answer...

given:

length of the lane=150m

breadth of the lane=9m

therefore are of the lane=l×b

=150×9

=1350m²

=135000cm²

length of the brick=22.5cm

breadth of the brick=7.5cm

area of the brick=l×b

=22.5×7.5

=168.75cm²

no. of bricks required to pave the lane=135000/168.75

=800

hence, 800brickes are required.

hope this helps...
