You do a^2 x b^2 = c^2 where a=the base, b= the height and c=the diagonal.
More info: take the square of "a" and the square of "b" and multiply them together, then take your answer and find the square root of it, that is "c" (the 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.
A 9 x 12 rectangle has a diagonal of 15.
yes if you want it to be a rectangle
The diagonal is 26cm
The diagonal is 14.21 cm
There are two of them.
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.
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.
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.
A diagonal cannot be a side of a rectangle, and a side cannot be a diagonal.
A 9 x 12 rectangle has a diagonal of 15.

You can calculate this using the Pythagorean formula for a right triangle.
The diagonal would be 12.53 meters.
If the diagonal is 25m and the area is 168m2 then the longest edge of the rectangle will be 24m.
Yes, the diagonal of a rectangle is X.
The diagonal is 14.21 cm
