Thread: ratio

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

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 m² (nearly 2 tennis courts).

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