(Mishnah - R. Eliezer): [If it was not Hukaf l'Dirah,] if its length exceeds the width, even by one Amah, one may not carry inside [more than four Amos];

R. Yosi says, even if the length is twice the width, one may carry inside.

(Gemara - Beraisa - R. Lazar): If the length was more than the width, even by one Amah, one may not carry inside.

This argues with R. Yonason (above (16b) he learned the Shi'ur from Chatzer ha'Mishkan. Its length was twice its width! - PNEI MEIR)

R. Yosah says, even if the length is twice the width, one may carry inside.

This supports R. Yonason.

What is the measure of Beis Rova (in which one sows a quarter Kav of seeds? A Mishnah (Kil'ayim 2:9) permits sowing different species in 24 patches, each a Beis Rova, in a Beis Se'ah.) It is a square, 10 and a half Amos by 10 and a half Amos;

R. Yosah says, [this Heter applies] even if the length [of the Beis Rova] is twice its width.
