We are talking right triangle here folks.
A**2 + B**2 = C**2
3*3 + 3*3 = C**2
18 = C**2
C = square root of 18, which is 3*3*2
C = 3 * square root of 2

The diagonal is called a hypotenuse. For problems like this where there is a right-angle, 90 degrees, you square the value of the sides. Since this is a square and one side is 3, the other outside side is also 3. The sum of those two sides squared (9 + 9) is 18. The square root of 18 is somewhere around 4.24 (the number continues to the right of the decimal, but it is not significant). This is a formula that is well over two millenia old.

according to pytaghoras theorem, a square + b square = c square
since a square has an equal length at all four ends,
a square + b square = 3 square + 3 square
= 9 + 9
= 18
whereby 18 = c square
hence c = square root of 18
approximately 4.2426

We can imagine a right-angled triangle having two of its sides 3. Then the third side will be square root of 18 .

In a square, the diagonal is always the length of a side multiplied with square root of 2.
in ur case 4,24

3 x 3 + 3 x 3 = 18
square root of 18 is 4.24
Good luck.

I need more details but use the midpoint formula or distance formula to determine length of diagonals.
