Question

Find the cost of flooring a room 6.4 m by 4 m with square tiles of side 16 cm at the rate of RS 3.50
per tile
​

Answer 1

Answer:

3500 rs

Step-by-step explanation:

Area of room = 6.4 × 4 m

= 25.6 m²

= 256000cm² ..... (i)

(since 1 m = 100 cm, 1 m² = 10000cm)

Area of tile = 16 × 16 cm

= 256 cm² ......... (ii)

From equating (i) and (ii),

Total tiles required = 256000/256

= 1000 tiles

Cost of flooring = 1000 × 3.50 rs

= 3500 rs

Answer 2

total tiles 1000

c. p of flooring 1000×₹3.50 =3500
