$\huge\green{\boxed{\green{\mathfrak{\fcolorbox{red}{black}{\underline{\pink{An}\blue{sw}\purple{e}\orange{r}\red{:}\green{-}}}}}}}$

Area of a room floor = 11*8 = 88m

Width of carpet = 0.55m

Let, length of carpet be = l

Area of a room = Area of a carpet

88 = 0.55*l

l = 88/0.55

l = 160m

Therefore the length of carpet required to cover the room is 160meters.

Answer 2

Answer:

Area of a room floor = 11*8 = 88m

Width of carpet = 0.55m

Let, length of carpet be = l

Area of a room = Area of a carpet

88 = 0.55*l

l = 88/0.55

l = 160m

Therefore the length of carpet required to cover the room is 160meters.
