If each interior angle is 4 times exterior angle then no of sides will be 10.

Explaination:

We know sum of exterior angles of any polygon is always equals to 360°.

=>Sum of interior angles = 360° * 4
=>1440°

We can find the sum of interior angles of every regular polygon by using

180×(n−2)

n is how much sides of the polygon. Example, triangle has 3 sides, so the sum of its interior angle is 180×(3−2)=180°180×(3−2)=180°

And now back to your question, if the sum of interior angles is 1440°, so:

180×(n−2)=1440

n−2=1440 /180

n−2=8

n=10

Hence, number of side = 10.
