The length of one side of a square with a 16-centimeter diagonal is: 11.31 cm
16*sqrt(2) = 22.627 (to 3 dp).
If you take the square of the long side and add it to the square of the short side, you get the diagonal (hypotenuse) squared. Then just find square root of that. For example, if short side is 3cm and long side is 4cm: 9 + 16 = 25, so the diagonal would be the square root of 25 ie. 5.
14 The ratio of the side of a square to the diagonal is 1.4.
side of a square is diagonal / 21/2
