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 ?
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 $\displaystyle 2.5\ m \times 4.0\ m$. In this case you don't need a compass to find your bed.
