    ratio

    A bed room of size 25x40 m is covered with a carpet which costs $140 . How much is 1 m of the carpet with width 18 m ?

    140/(25x40)=0.14 ... This is the cost of 1x1 m of the carpet .

    Then 18x1 of the carpet will be 0.14x18=2.52

    Am i correct ?

    25 x 40 metres = 1000 square metres

    1000 square metres = $140

    1 square metre = $0.14 same answer as you

    1 metre of carpet with width 18 m = 18 square metres

    18 x $0.14 = $2.52 same answer as you

    I believe your working to be correct

    I don't know where you live but in Germany there isn't a bed-room of 1000 mē (nearly 2 tennis courts).

    Could it be that there are some decimal points missing and the bed-room has the demensions 2.5\ m \times 4.0\ m. In this case you don't need a compass to find your bed.
