There are no diameters for squares; let us just make that clear. Diameter only applies for circles (Line that goes through centre of circle and touches edges). However, diameters in squares would be simply length(but went through centre). Therefore it could be anywhere between 15-~21.2132. (Straight length/width or diagonal or anywhere else.)

Hope this helps :D
