Question

How many numbers lie between the square of the given numbers $12$ and $13$?

Answer 1

Find the required numbers

The two given numbers are $12$ and $13$

Square of $12$ is ${12}^2=144$

${13}^2=169$

Now, numbers lying between two numbers $\mathrm{a}$ and $\mathrm{b}$ are $\left(\mathrm{b}-\mathrm{a}\right)-1$

So, numbers lying between $144$ and $169$ are $\left(169-144\right)-1=25-1$

$=24$

Hence, the numbers lying between square of $12$ and $13$ are $24$.
