Question

10. A courtyard 25.5 m long and 16 m board is to be paved with bricks of length 34 cm and breadth 20 cm. Find the number of bricks required.​

Answer 1

Answer

• Number of bricks required => 6000

Given

• A courtyard 25.5 m long and 16 m board is to be paved with bricks of length 34 cm and breadth 20 cm.

To Find

• The total number of bricks required to pave the courtyard.

Step By Step Explanation

Given that a courtyard 25.5 m long and 16 m board is to be paved with bricks of length 34 cm and breadth 20 cm.

We need to find the total number of bricks required to pave the courtyard.

So let's do it !!

1 m = 100 cm.

Therefore,

25.5 m => 2550 cm

16 m => 1600 cm

So let's do it !!

$\maltese\bold{\boxed{\mathfrak{\pink{Area_{(Rectangle)} = Length \times Breadth}}}}$

$\dag \boxed{ \bf{ \green{Number \: of \: Bricks = \cfrac{Area \: of \: Courtyard}{Area \: of \: Brick}}}}$

By substituting the values

$: \longrightarrow \sf\cfrac{ \cancel{2550} \times \cancel {1600}}{ \cancel{20} \times \cancel{34}} \\ \\ : \longrightarrow \sf6000$

Therefore number of bricks required = 6000
