Question

hi there

a lane 150 M long and 9M wide is to be paved with bricks each measure 22.5 CM by
7.5 cm find the number of bricks required

Answer 1

$<b><u>$

Area of lane = l*b= 150*9=1350m²

area of brick=22.5*7.5=168.75cm²

=0.016875m²

number of bricks required=area of lane / area of brick=1350/0.016875m²

                                        =8000 bricks

        so, 8000 bricks are required
                     

Answer 2

Hey dude here's your answer:
Lenght of the lane = 150M
Breadth of the lane = 9M
Area of the lane = l*b
= (150*9)M
= 1,350M
1m = cm
1,350m = 1,350*
= 1,35,000cm
Length of the bricks = 22.5cm
Breadth of the bricks = 7.5cm
Area of the bricks = L*B
=(22.5*7.5)CM
=168.75cm
No. of bricks required to pave the lane =
Area of lane/Area of bricks
= 800bricks
Therefore, no. of bricks required to pave the lane = 800bricks
Hope it helps you
