Resistance is directly proportional to length and inversely proportional to area. So when length become half resistance will be half just in your case it will become 5(half of 10) and resistance is inversely proportional to area so by doubling area resistance will be half and (half of 5) resistance will be 2.5 Ohm. And that's the answer.
