what will be the resistance of a conductor when it's length and area of cross section is doubled from original?

The question that rises to mind is: Was the width decreased? When you say “stretched,” I imagine someone literally stretching a wire; making it twice as long, but half as thick.
I'll assume what you meant was: Would a wire, that is twice as long, have a difference in resistance? The reason for this is because you specifically mentioned the wires length being doubled in the question, but nothing about the width. I suspect that English is a second lauguage. That's ok. I've answered both questions. YES! The resistance would also be doubled. It be the same as putting two like resistors in series instead of one.
If you did “streach” a wire, lowering the width by half and doubling the length, the resistance would be quadrupled.(×4)

it will remain the same the value of resistance does not change
