1. 64

2. 128

3. 256

4. 32

EVALUATION

Here the side of the square hall = 8 m

So side = 8 m = 800 cm

Area of the floor of the square hall

= 800 × 800 cm²

= 640000 cm²

Now side of each tiles = 50 cm

So area of each tiles

= 50 × 50 cm²

= 2500 cm²

Hence the required number of tiles

= 640000 ÷ 2500

= 256

Step-by-step explanation:

Given

• Side of tile = 50 cm
• Side of square hall = 8 m

To find

• How many tiles are required to floor the square hall.

Solution

⇒ Side of square hall = 8 m

⇒ Side of square hall = 8 × 100 cm

• 800 cm

⇒ Area of square hall = side × side

• 800 × 800
• 640000 cm²

⇒ Side of each tile = 50 cm

⇒ Area of each tile = 50 × 50

• 2500 cm²

⇒ Number of tiles = Area of square hall/Area of each tile

• 640000/2500
• 256

∴ Number of tiles are 256.
