Each of them is 14.14 inches long. (rounded)
A square with a 30-inch diagonal measurement has sides of 21.21 inches in length.

A parallelogram is anything from a square to a rectangle. As long as it has parallel sides, then it is a parallelogram. If you're thinking of a rhombus, then it has diagonal sides.
They came from geometry. If you have a square whose sides are 1 unit long then its diagonal is sqrt(2) units long.

Use Pythagoras. The diagonal, and two sides of the square form a right angled triangle. So if each side of the square is x cm long, the diagonal is x*sqrt(2) cm long.

They came from geometry. If you have a square whose sides are 1 unit long then its diagonal is sqrt(2) units long.
A square has 4 equal sides. A rectangle has 2 short sides of equal length and 2 long sides of equal length
If the area of the square is 200, then the side is sqrt(200).The length of the diagonal is sqrt(200 + 200) = sqrt(400) = 20 meters.
Using Pythagoras' theorem each side will be 6.363961031 units in length.
The diagonal is 14.142 feet.
The diagonal is 33.941 units.
