The Correct Option is B
Solution and Explanation
Assume the number of sides of the polygon be \(n\)
The Sum of interior angles of any polygon = \((n - 2) ×180 = 1620\)
= \(n - 2 = \frac{1620}{180}\)
= \(n - 2 = 9\)
= \(n = 11\)
So, The number of sides of the polygon is 11
The correct option is (B): 11
