witch is a better approximation of the square root of twenty 4.5 and 4.47 explain because i dont know?​

4.47

Step-by-step explanation:

What square  roots are having √20 in between them?...

√16 = 4                         √20 ≈ a number between 4 and 5         √25=5

║                                       ║                                                                ║

 16 is 4 away from  20                     25 is 5 away form 20

so √20 is closer to √16 (=4)  

so a better approximation is the one closer to 4

so is 4.47

50x5=$250
