Question

find the length of a lane 5 m wide which can be covered by 50000 bricks of size 22 cm by 15 cm

Answer 1

Heya friend,


Here is your answer,

Width= 5 m (given)

No of bricks= 50,000 (given)

Area of per bricks = 22cm × 15cm = 330 cm² (given)

=> Area of 50,000 bricks = 500000 × 330 cm² = 16500000 cm²

=> 16500000 cm² = 1650 m²

So, the area of lane = 1650 m2

Now, since

=> Width = 5 m

=> Length = area/width

=> Length of lane = 1650 m²/ 5 m = 330 m

Thus,

The length of the lane = 330 m (ans)



Hope it helps you.
Thank you.

Answer 2

hey....!

here's ur answer....!

area of the lane=area of 50000bricks

given length of the brick is 22cm and breadth is 15cm.

area of one brick=l×b

=22×15

=330cm²

therefore area of 50000bricks=50000×330

=16500000cm²

in metres=16500000/100×100

=165000m²

hence the area of the lane is also 1650m²

if width of the lane is 5m then length is:-

l×b=1650m²

l×5=1650m²

l=1650/5

l=330m

verification:-

area of lane=l×b

=330×5

=1650m²

hence verified.

thus, the length of the lane is 330m

hope this helps...!
