if the area if a square is 64 cm^2,what is the length of the diagonal of the square.
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....
+1713 First find the sides of the square:
\(\sqrt{64} \\Then\ you\ should\ use\ the\ Pythagorean\ theorem\ to\ get\\ \\\sqrt{64+64} \\\sqrt{128} \\8\sqrt{2}\)
Thats your diagonal:
8sqrt2
