Answer 1

Answer:

• Required tiles = 40,000
• Total cost of tiling = ₹12,00,000

Step-by-step explanation:

Question says that, Find the number of tiles of (25 × 25)cm² required for tiling a Hall of 2500m². And also, Find the total cost of tiling of at the rate of ₹30 per tile.

Step 1 : Find the required tiles

Given,

• Dimensions of a tile : (25 × 25)cm² or, (0.25 × 0.25)m²
• Area of the hall : 2500m²

Required tiles is given by :

→ Area of the hall ÷ Area of a tile

→ 2500 ÷ (0.25 × 0.25)

→ 2500 ÷ 0.0625

→ 40,000

The number of tiles required is 40,000

Step 2 : Find the cost of tiling

[unitary method]

If one tile costs ₹30

Then, 40,000 tiles will cost 30*40,000

= ₹12,00,000

The cost of tiling the floor is ₹12,00,000

Note behind:

• We need to convert the dimensions in same units for the calculation.
