There are 275 diagonals in a 25 sided polygon
There are 275 diagonals in a shape with 25 sides. The formula is n*(n-3)/2
(25-2)*180 = 4140 degrees
1/2*(252-75) = 275 diagonals
0.5*(25-15) = 5 diagonals
If: 180 -165.6 = 14.4 degrees for each exterior angle Then: 360/14.4 = 25 sides So: 0.5*(25^2 -3*25) = 275 diagonals

Yes, if the shape happened to be a pentagon ( 5 sided figure ) , each side could be 5 meters and 5 times 5 is equal to 25.
25 of the 33 existing states in the United States had sided with the union by the end of the Civil War.
A 25-sided shape would have no parallel sides !
25 is 25% of 100 unless you have another figure in mind
