Answer:

  • 11 is sides of polygon

Given :

  • The sum of the interior angles of a polygon is 1620⁰

To find :

  • Sides

Solution :

we know that, Sum of interior angles of n - sided polygon is

  • (n - 2) × 180

where , n is number of sides

Given , The sum of the interior angles of a polygon is 1620⁰ then,

》(n - 2) 180 = 1620

》(n - 2) = 1620/180

》n - 2 = 9

》n = 9 + 2

》n = 11

Hence , 11 is sides of polygon

Verification:

As we know that

  • (n - 2) × 180

Where , n is 11

》(11 - 2) × 180

》9 × 180

》1620

Hence verified
