Between which rational number does the square root of 30 fall

2.1 I believe.  So sorry if I'm wrong

The closest perfect squares to 30 are 25 and 36, which are the squares of 5 and 6, respectively. So the square root of 30 is going to fall between 5 and 6. Also, because 30 is closer to 25 than 36, the square root of 30 is going to be between 5 and 5.5.
