my number is less than 30
my number will make a square array
my number is________?
I was not sure where to begin with this word problem - can you help??

Hi,

The number is between 5 and 30. The number can be put into a square array so the number is a square.

What numbers between 5 and 30 are squares?
Which off these can be put into an array which is 2 rows wide?
