The method of finding the sum of the interior angles of a polygon is by multiplying the (number of sides)-2 by 180, so the sum of the interior angle measures in a 25-sided polygon would be 23*180, or 4140 degrees.

It can be hard learning and memorizing all the name of the different polygons. A 25 sided shape is called icosikaipentagon.

A 25-sided polygon is an icosikaipentagon, an icosipentagon, or icosapentagon.It is also acceptable to call it a 25-agon.A 25 sided shape is called an icosikaipentagon.icosakiatatriagonmost people call it a 25-gon
1/2*(252-75) = 275 diagonals
The formula to find the total amount of degrees contained by a shape is (n-2) * 180, where n is the number of sides. So, 25 - 2= 23, and this times (*) 180 is 4140, so the total of the internal angles of a 25-sided shape is 4140.
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.
0.5*(25-15) = 5 diagonals
(25-2)*180 = 4140 degrees
