Question

Answer 1

☆Hello friend☆

Lets take out area of ractangular floor i.e., =L×B
= 3.5m×2m= 7.0m^2

Convert m^2 into cm^2= 70000cm^2

Cost of tilling per sq cm= Rs 50
Cost of tilling floor= Rs 50 ×70000
=Rs 35,00,000

Answer 2

First we need to convert the mesurements into cm.
3.5 m=3.5 *100 cm=350 cm
Also, 2m=2*100 cm=200 cm
Area of bathroom=350*200=70000 cm²

For 1cm² titling cost= Rs. 50
For 70000 cm² tiling cost= Rs.50* 70000 =Rs. 3,50,000.
