All sides are equal in a square

x = side length

x * x = area

x*x =64

x = 8 cm       Now use the pythagorean theorem to find the diagonal....

a right triangle with two legs , each = 8    and the diagonal is the hypotenuse.    You can do it....

First find the sides of the square:

$$\sqrt{64} \\Then\ you\ should\ use\ the\ Pythagorean\ theorem\ to\ get\\ \\\sqrt{64+64} \\\sqrt{128} \\8\sqrt{2}$$
