9 stripes. because 0.6858 cm (if that would matter) would be left uncovered if you only have 8. and i presume you cannot buy a fraction of a stripe, right?

first, you need to convert the meters into cm... you multiply 5.5 by 100 (since there are 100 cm in a meter).
So, now you have 550cm for the room size.
Now, you can set up a proportion:
68.58cm/1 piece carpet = 550cm/x pieces carpet
Then, solve for x...
x(68.58cm)=550cm
x=550cm/68.58
x=8.0198...Since there would be .0198 left uncovered with only 8 pieces, you would need 9 pieces of this specific carpet to cover the room.

width of room = 5.5 *100=550cm
width of a piece of carpet = 68.5cm
therefore no. of stripes required = 550/ 68.58= 8.0165=9cm

550 / 68.58
