The correct answer is: 900°
Explanation:
As it is mentioned in the question that the figure (attached) has seven-sided polygon (n=7), we can find the sum of interior angles of that polygon as follows:
Sum of interior angles = (n-2) * 180° --- (A)
Where, n=7 (as mentioned above); plug in the value of n in (A):
Sum of interior angles = (7-2) * 180°
Sum of interior angles = 900°
Hence, the sum of interior angles is 900° (Option A).
