find the diagnol length of a squares:
a square have all sides equal length
we usually mark them with an a, and diagonal with d

as you can see, diagonal divides square into two right triangles and you use Pythagorean theorem to find the diagonal length of a square
d%5E2=a%5E2%2Ba%5E2=2a%5E2 if you are given a
or the side length
a%5E2=d%5E2%2F2 if you are given d
