Answer 2

Answer:

Now, there are a total of 55 diagonals possible for an 11-sided polygon which includes its sides also. So, subtracting the sides will give the total number of diagonals contained by the polygon. So, total diagonals contained within an 11-sided polygon = 55 -11 which is equal to 44.
