Suppose the polygon has n sides. Then n*(n-3)/2 = 54 or n*(n-3) = 108 and so, by inspection, n = 12 or you can multiply out the brackets and solve the quadratic equation in n.
It is abs(54 - 7*n) or |54 - 7*n|
75 n
(n - 2) times 180 degrees. Triangle: n=3, n-2=1 ===> 180 degrees Square: n=4, n-2=2 ===> 360 degrees etc.
Sum of degrees of angles in a n-gon = (n-2)*180 degrees, where n = sides nona- = 9 sides, so n = 9 (9-2)*180 degrees = 1260 degrees. 1260 degrees total/9 sides = 140 degrees per side

Vatican City, Rome, Italy. 41 degrees 54' 10.59" N : 12 degrees 27' 12.28 E
These coordinates fall within Bangladesh, near or within the Gaurnadi subdistrict.
If they are equal numbers then n = n Hence n + n = 54 2n = 54 n = 54/2 n = 27 So 27 + 27 = 54
