Along the length is simple to find. Cut the 60 into 6 parts, and you put 10+1 on each LENGTH, being here 22 pillars.

Be aware that the ends of each width now have their pillars already.

Width: 2880%2F60=288%2F6=144%2F3=12%2A3%2A4%2F3=48;
The width of the garden is 48 meters.
Cut 48 into increments of 6, and there are 8 of these increments. If placing pillars on all these width locations would be 9; but 2 on each width are already placed. This means you place 9-2=7 pillars on each width, or because TWO widths make the garden, 14 pillars.

Total count of pillars, 22%2B14=highlight%2836%29.
