$\huge\underline\bold\orange{Answer:}$

It is clear from the attachment that

252 = 2 × 2 × 3 × 3 × 7

We can see that the number 7 doesn't form a pair.

We need one more 7 so that It forms a pair

So,

We have to multiply 7 to 252 for a perfect square

252 × 7 = 1764

Now Square root of obtained number:

$\sqrt{1764} = \sqrt{42 \times 42}$

$\sqrt{1764} = 42$
