So,
Therefore, the correct option is (a) 30 mph.
Given:
The number of sides of given polygon = 4
To find the sum of the interior angles of the polygon.
Formula
The sum of interior angles of any polygon is
where, n be the number of sides of the polygon.
Now,
Taking n = 4 we get,
or,
or,
Hence,
The sum of the interior angles of the polygon is 360°.
