Question

solve this questio fast and correct

Answer 1

Given Length of lane = 150m = 15000cm.

Given width of lane = 9m = 900cm.

Area of lane = (length * breadth)

= > 15000 * 900

= > 13500000 cm^2

-----------------------------------------------------------------------------------------------------------------

Given, length of the brick = 22.5 cm

Given, width of the brick = 7.5cm.

Area of brick = (length * breadth)

= > (22.5 * 7.5)

= > 168.75 cm^2

----------------------------------------------------------------------------------------------------------------

Now,

Number of bricks required = Area of lane/Area of brick

= > 13500000/168.75

= > 80000.

Therefore, Number of bricks required = 80000.

Hope it helps!
