'Squared' in the Bible

And he measured the courtyard [as to its] length, a hundred cubits, and a hundred cubits wide, squared, and the altar {is in front of} the temple.

The posts of the temple were squared, and the face of the sanctuary; the appearance of the one as the appearance of the other.

And the altar hearth [was] {twelve} [cubits] [in] length and {twelve} [cubits] [in] width; [it was] {squared on its four sides}.

And [there] shall be from this [area] five hundred [cubits] by five hundred [cubits], squared all around, for the sanctuary; and fifty cubits [of] open space [shall be] for it all around [it].
