Let x equal the length of the square. Let y equal the length of the diagonal. Two times (x squared) = (y squared).
Answer:
You have to use Pythagorus' relationship of the sides of a right angled triangle to the hypotenuse.
It states that the sum of the squares of the sides (A2 + B2 ) equals the square of the hypotenuse (C2):
A2 + B2 = C2
In the case given, the hypotenuse is the diagonal of the square and the sides are all equal so
A2 + A2 = C2
or 2A2 = C2
reorganizing to get the length of the diagonal on one side:
SQRT(C2) = SQRT (2A2) = SQRT 2 x SQRT A2
or C = SQRT 2 x A
The side is therefore always the length of the diagonal divided by the square root of 2 (approximately 1.1442)

The area of a square is 100 The length of its diagonal is approximately?
If the area of a square is 100, then its side length is 10. If we draw in a diagonal, then we know by the Pythagorean formula that the diagonal's length is sqrt(10^2 + 10^2) = sqrt(200) = 10*sqrt(2).The square root of 2 is approximately 1.414, so the diagonal's length is approximately 10*1.414 =14.14* The diagonal of any square is the side length times (sq rt 2).
If a square is inscribed in a circle the diameter of the circle is congruent to?
The diameter of the circle is congruent to the length of the diagonal of the inside square. If you know the length of one side of the square, you can use pythagorean's theorem to solve for its diagonal (hypotenuse) and thusly the square's diameter.

How do you find the width and length of a rectangle if you only know the diagnol?
If the only known fact is the length of the diagonal then the width and length of the rectangle CANNOT be determined. The diagonal could be that of a square, or of a rectangle that is very long but quite narrow. Consequently at least one more fact is required such as; the dimension of either the length or the width, or the angle that the diagonal makes to the base of the rectangle or even the area of the rectangle.
