Hence, This is in the form of Rectangle.
=> Area of lane = l x b
=> Area = (150 x 9) m^2
=> Area = 1350 m^2
Now,
=> Area of Brick = l x b
=> Area = (0.225 x 0.075) m^2
=> Area = 0.016875 m^2
Number of bricks = Area of Lane/Area of Brick
=> No. of bricks = (1350/0.016875)
=> No. of bricks = 80000 bricks
=> Area of lane = l x b
=> Area = (150 x 9) m^2
=> Area = 1350 m^2
Now,
=> Area of Brick = l x b
=> Area = (0.225 x 0.075) m^2
=> Area = 0.016875 m^2
Number of bricks = Area of Lane/Area of Brick
=> No. of bricks = (1350/0.016875)
=> No. of bricks = 80000 bricks
