Explain how you know that the square root of 225 is between 10 and 20.

Question

im doing square roots in mTH CLASS IM IN GRADE 7

Answer 1

well, 10 squared is 100

and 20 squared is 400.

 

Since you are looking for the square root of 225, its- between 10 and 20.

furthermore, you can constraint it more....

as 14 ^ 2 = 196 and 16 ^ 2 = 256... and the 225 is between the 196 and 256 :)

Hope it helps.

Answer 2

225/15=15!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 3

The square root of 225 must be between 10 and 20 because if you tried to square anything below 10 or 10 it would be too low , if you tried to square higher than 20 or 20 it would be too high. So the square root must be inbetween.,
