Halakhah for Eruvin 46:13
קרפף שהוא יותר מבית סאתים שהוקף לדירה נזרע רובו הרי הוא כגינה ואסור
And if we had been told, 'The halachah is in agreement with R'Akiba' it might have been assumed that [an enclosed area that was] long and narrow is not [permitted],<span class="x" onmousemove="('comment',' Since R. Akiba required a squared area.');"><sup>22</sup></span> hence we were also informed that 'the halachah is in agreement with R'Jose'.<span class="x" onmousemove="('comment',' That a non-squared area is also permitted.');"><sup>23</sup></span>
Sefer HaChinukh
And since we explained the shekel-coins, it is fitting that we explain how much is a chomer: You should know that the chomer is a measure that is [also] called a kor. And a kor is two letech, and a letech is fifteen seah. It comes out that a chomer is thirty seah, which is ten eipah - as an eipah is three seah. It is a well-known thing and we also already knew it from our Rabbis, may their memory be blessed, (Eruvin 23b) that a place that has fifty ells by fifty ells is a beit seah - meaning that it is [what contains what grows from] a seah of barley - and that is two thousand five hundred [square ells] by arithmetic (multiplication). It comes out that a place that is fitting for the seed of a chomer of barley - which is thirty seah - is seventy-five thousand ells by arithmetic.
