Question

The sum of all interior angle of a polygon of 7 side is

Answer 1

Given ,

The number of sides of polygon is 7

We know that ,

The sum of all interior angles of polygon with n sides is given by

$\mathtt{ \large \fbox{Sum = (n - 2) \times 180 }}$

Thus ,

Sum = (7 - 2) × 180

Sum = 5 × 180

Sum = 900

Hence , the sum of all interior angles of polygon is 900
