20 I apologize if this is wrong
For a rational number to have a terminating decimal expansion
q should be in the form 5^m and 2^n or both. If q is not in the form of either then it is a non terminating recurring decimal expansion
As you can see from the polygon, 70/10= 7.
The second polygon is an enlargement of the first one.
Just multiply 4*7 to get the answer.
4*7= 28
That's the answer!
I hope this helped you!
Brainliest answer is always appreciated!
