Length of the room=15 m 17 cm= 15*100+17= 1517 cm.

Breadth of the room= 9 m 2 cm= 902 cm.

The HCF of 1517 and 902 will be size of square tiles.

HCF 1517 and 902 = 41 cm.

Area of the room=length × breadth
=1517*902 cm2

Area of tiles=41, *41 cm2

So, number of tiles required

frac1517*90241*41

814 Tiles
