Question

How many bricks, each 25 cm long and 12 cm broad will be needed to pave a court 30m
long and 20m wide?​

Answer 1

Answer:

Step-by-step explanation:

To pave a court 30 metre long and 22 metres wide, 200 bricks of each 22 cm long and 15m broad will be required.

Step-by-step explanation:

The length of the court = 30 m

The width of the court = 22 m

∴ Area of the court = length * width = 30 m * 22 m = 660 m²

Also,  

The length of each brick = 22 cm = 0.22 m

The breadth of each brick = 15 m

∴ Area of the each brick = length * breadth = 0.22 m * 15 m = 3.3 m²

Thus,  

The no. of bricks required to pave the court are,

= [Area of the court] / [Area of the each brick]

=  

= 200
