Realize that to get the area you have to take length time width.
So, since this is a square, the length and the width is 6.

Now, you want the diagonal.
a^2+b^2=c^2
6^2+6^2=c^2
36+ 36 = c^2
72=c^2
c = square root of 72

72 is not a perfect square, but this can be be reduced
72 = 8 *9. 8 is not a perfect square, but can be reduced again, 9 is a pefect square
So square root of 72 = square root of 9 *4*2
Square root of 9 is 3 and square root of 4 is 2
So Square root of 72 = 6 square roots of 2 is the diagonal of the square.

square=36
Length[L]=Width[W]=Square root of 36
L=W=6

Diagonal of square

D^2=L^2+W^2
D^2=6^2+6^2
D^2=36+36
D^2=72
D=SQRT(72) square root of 72
D=8.4852813742385695
D=8.485
