Question

The length and breadth of a rectangular hall are 50m and 30 m respectively Rectangular tiles with length 50 CM and breadth 40 CM are to be paved on its floor find the number of tiles required

Answer 1

Given :

Length of Rectangular hall = 50 m

Breadth of Rectangular hall = 30 m

Finding Area of Rectangular hall -

Area = length x breadth

Area = 50 m x 30 m

Area = 1500 metre²

Area of a Rectangular hall = 1500 metre²

Given :

Length of each tile = 50 cm

Breadth of each tile = 40 cm

Converting CM to M -

1 metre = 100 cm .

50 cm = 50/100 = 0.5 m

40 cm = 40/100 = 0.4 m .

Finding Area of each tile -

Area = length x breadth

Area = 0.5 m x 0.4 m

Area = 0.2 metre²

Area of each tile = 0.2 metre² .

Finding number of tiles required -

If , each tile = 0.2 metre² .

1500 metre² = ? tiles

= 1500 / 0.2 = 7500

= Area of 1500 metre² required 7500 tiles tiles.

Answer : Number of tiles Required = 7500 .

Answer 2

$\huge \underline \mathbb {SOLUTION:-}$

Given:

• The length and breadth of a rectangular hall are 50m and 30 m.

Need To Find:

• Area of rectangular hall = ?

Formula used here:

• Area = L × B

Putting the values according to the given formula:

➠ Area = 50m × 30m

➠ Area = 1,500m²

• Hence, the area of rectangular hall is 1,500m²

$\setlength{\unitlength}{1.0 cm}}\begin{picture}(12,4)\thicklines\put(1,1){\line(1,0){6.5}}\put(1,1.1){\line(1,0){6.5}}\end{picture}$

Now,

Given:

• Rectangular tiles with length 50 CM and breadth 40 CM.

Need To Find:

• Area of each tile = ?

Firstly,we have to convert centimetre to metre.

As we know that,

• 1m = 100cm

Therefore,

➠ 50cm = 50/100

➠ 0.5m

➠ 40cm = 40/100

➠ 0.4m

$\setlength{\unitlength}{1.0 cm}}\begin{picture}(12,4)\thicklines\put(1,1){\line(1,0){6.5}}\put(1,1.1){\line(1,0){6.5}}\end{picture}$

Now,

• Find the area of each tile. = ?

Formula used here:

• Area = L × B

Putting the values according to the given formula:

➠ Area = 0.5m × 0.4m

➠ Area = 0.2m².

$\setlength{\unitlength}{1.0 cm}}\begin{picture}(12,4)\thicklines\put(1,1){\line(1,0){6.5}}\put(1,1.1){\line(1,0){6.5}}\end{picture}$

Now,

We have to find the number of each tile. = ?

Suppose, each tile = 0.2m².

Then, 1500m² = ? Tiles

➠ 1500/0.2

➠ 7,500

• Hence, area of 1,500m² required 7,500 number of tiles.

Additional Information:

Here:

• L is used for Length.
• B is used for Breadth.
