Too small to see at this scale. The ring marks its true-scale position, not its area. The shape has not been enlarged.
Both shapes share one area scale. Known rectangular footprints keep their physical sides. Other shapes are equal-area squares, not maps; they do not prove a physical fit.
A little perspective
1 square metre is approximately equal to the area of a sheet of A0 paper.
