Question

a
14. A coaching institute wants to execute tiling work for one of its teaching halls 60 m long and 40 m wide with
square
tile of 0.4 m side. If each tile costs = 15, the total cost of tiles would be
​

Answer 1

Step-by-step explanation:

Number of tiles required :

=Area of hallArea of each tile=(60×400.4×0.4)=15000

∴ Total cost of tiles :

= Rs. (15000 × 5)

= Rs. 75000

Answer 2

Tottal number of tiles = Area of hall/ Area of Tiles

$= > number \: = \frac{60 \times 40}{0.4 \times 0.4} = \frac{2400}{0.16}$

$= > number = \frac{240000}{16} = \frac{60000}{4} = 15000$

Total cost of tiling = Number of tiles × cost of one tile

$= > cost \: = 15000 \times 15 = 225000$

Hope this answer helps you ^_^ !
