Translation of "Lengths" in Arabic

They trade off lengths - nothing astonishing has happened yet -

إنهما يتبادلان الطول -لا شيء مدهش حصل بعد-

And went on fast for various lengths of time,

وقاموا بالصيام لفترات زمنية مختلفة،

Had gone to extraordinary lengths to hide her identity.

قد بذلت جهوداً كبيراً لإخفاء هويتها.
