IF YOU EXPLAIN IT I WILL MARK YOU BRAINLIEST!!

Answer 1

1m = 100 cm

Formula:

$no \: of \: tiles = \frac{area \: of \: room}{area \: of \: tiles} \\ = \frac{9.68 \times 6.2 \times 100}{22 \times 10 } \\ = \frac{6001.6}{220} \\ = 27.28$

The no of tiles used is 27.28

Price of 1 tile = 2.50 rs

Price of 27.28 tiles = 27.28×2.50=68.2 Rs
