Answer :
I'm not completely sure which way they would like for you to do it
but anyways
3 to 15 is a times 5
so 5 times 5 is 25
so a possible width can be 25
as in 15 by 25
or
5 to 15 is times 3
so 3 times 3 is 9
so a possible width can be 9
as in 15 by 9
I personally think 25 inches wide would be the better answer
