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.

How do you calculate dimensions of a rectangle when given diagonal?
You don't - you need additional information. Many different rectangles can have the same diagonal. If you know the diagonal and one side (which must be LESS than the diagonal), you can use Pythagoras' Theorem to calculate the other side.
What is the diagonal if a rectangle is 9 x 12?
A 9 x 12 rectangle has a diagonal of 15.

Calculate diagonal of rectangle?
There are two of them.
How do you calculate the diameter of a rectangle?
A rectangle does not have a diameter, as such, but the diagonal is similar enough. If the sides of a rectangle are x cm and y cm then, using Pythagoras's theorem, the diagonal is sqrt(x2 + y2) cm.
The diagonal of rectangle is citizen its grade is 37 then the perimeter is?
You CAN'T calculate the perimeter of a rectangle, knowing only its diagonal. You do need some additional information about the rectangle - such as its width, or its length, or perhaps the length/width ratio.
How do you calculate dimensions of a rectangle when given diagonal?

How many diagonal sides does a rectangle have?
A diagonal cannot be a side of a rectangle, and a side cannot be a diagonal.
