- Mia and Lily are trying to find the nearest whole number to the square root of 120

Mia: It is 10
Lily: It is 11

Who is correct?

Give a reason for your answer.​

Answers

Lily is correct

11x11=121 and 10x10 is 110 so the nearest number of the square root 120 is 11.

For determining the nearest whole number for the square root of 120, the Lily is correct i.e. it is a square of 11.

Given that,

Mia has 10 number.And,  Lily is 11 number.

Now if we square both the numbers so it comes:

10^2 = 10011^2  = 121

So, 121 is nearest to 120.

Therefore we can conclude that for determining the nearest whole number for the square root of 120, the Lily is correct i.e. it is a square of 11.
