Answer: 19.3
Step-by-step explanation: To solve this we can find numbers whose squares are close to 372. We know 20x20 = 400 and 19x19 = 361 so it has to be between these two.372 is closer to 361 meaning the square root of it is less than 19.5. Now we can just test numbers. 19.4x19.4 = 376ish and 19.3x19.3 is 372.49. This number is close enough so 19.3 is our answer.
