Answer 1

Answer:

01. 1000 tiles are required to cover the floor and,

02. The cost for tiling the floor will be Rs.99,900.

Step-by-step explanation:

The Dimensions of the floor is given as 3m*2m.

The area of the floor is 6m².

The Dimensions of tile are 10cm*6cm.

The area of the tile is 60cm².

01. Number of tiles = $\frac{Area of floor}{Area of tile}$

⇒Number of tiles = $\frac{6}{60*10^{-4} }$         ∵1cm²=10⁻⁴m²

⇒Number of tiles = $\frac{1}{10*10^{-4} }$

⇒Number of tiles = $\frac{1}{10^{3} }$

⇒Number of tiles = 1000

02. Given the cost for every 10 tiles is Rs.999

Cost for 1000 tiles=$\frac{1000}{10}$ *999

⇒Cost for 1000 tiles=100*999

⇒Cost for 1000 tiles= Rs.99,900
