Most that I've seen are 14 ft wide.
Varies by state. 16' here in SC.
The dimensions are dependent upon the overall size, length and width, of the double-wide mobile home in question.
No, an RV is able to move under it's own power and leave to go immediately. A mobile home is 'mobile' only in the sense it can be towed to a park. They have no motive power. In most cases they are placed on block foundations and wheels and axles are removed.
Usually you disconnect sewer and incoming water and electricity, then jack it up, and re-attach axles and the tow bar.
Practically nobody. You might find a buyer but I'd highly doubt it. Your best bet is selling it to a metal scrap yard.
If the nuts won't turn, then i would grind them off with a cutting disc, or just burn them off with a cutting torch.
You multiply the width by the length to get the area. In this case the answer would be 1440 square feet in the home.
