Let n be the number of sides of polygon such that sum of the interior angles is 1260°.

= (2n - 4) [Right Angle]

= [(2n - 4) × 90°]

= (2n - 4) × 90° = 1260°

$= 2n \: - \: 4 = \frac{1260}{90} = 14$

= 2n = 14 + 4

= 2n = 18

= n = 18 ÷ 2

= n = 9

Hence, the number of the sides of the polygon are 9
