Question 85978
we know that for a 'n' sided polygon, the sum of interior angles is (2n-4)*90.. at the same time, we also know that the sum of exterior angles of a polygon is always 360 degrees. from the question we understand that:
(2n-4)*90 = 6*360
or 2n-4 = (6*360/9) = 24
hence 2n=28
hence n=14

Therefore the polygon has 14 sides.
