Answer 1

the cost for tiles are Rs. 15000

Answer 2

Answer:

Rs.15000

Step-by-step explanation:

Side of square room = 10 m

1 m = 100 cm

So, 10 m = 1000 cm

Side of square room = 1000 cm

Area of floor = $Side ^2$

                     = $(1000)^2$

                     = $1000000$

Area of tile = $25cm*20cm$

                  = $500 cm^2$

No. of tiles required = $\frac{1000000}{500}$

                                  = $2000$

Cost of 1 tile = Rs. 7.50

Cost of 2000 tiles= $7.50 \times 2000$

                              = $15000$

Hence the cost of flooring the room is Rs.15000
