Estimate each square root to the nearest whole number.

$\sqrt{112}$

The square root to the nearest whole number is 11.

1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169….

112 lies between 100 and 121.

Distance of 112 from 100 = 112 – 100 = 12

Distance of 112 from 121 = 121 – 112 = 9

Since 9 < 12. So, 121 is closer to 112.

We know $121={11}^{2}$. So, $\sqrt{121}=11$.
