The 2 square numbers closest to 56 are 49(7x7) and 64 (8x8)

So the square root is somewhere between 7 and 8

56 is 7 away from 49 and 8 away from 64 so we know the number will round to 7 but be fairly close to 7.5.

A good estimation would be 7.4

It’s asking you to round to the nearest integer (no decimals) so this would be 7

Because square roots are both positive and negative and it’s asking for it as an integer (includes negative numbers), the answers is +7 or -7. Both are the correct answer
