I am sorry but could you explain to me why " the band is seven meters long". - is not excepted here.... please.
Never mind, it just wasn't on the list for some reason... Fixed now.
Just make sure you know that it means "band" in the sense of a wide flat long often circular thing (like a rubber band, ribbon, or conveyor belt).
'Meter' in English is 'Metre' not 'Meter!
