Both power units and trailers come in many lengths. Bear in mind, a semi-trailer is simply a trailer which does not wholly support its own weight - thus, boat trailers, equipment trailers, etc. are semi trailers. But, for the sake of argument, we'll assume you're referring to a semi-trailer of the type intended to be pulled by a Class 8 truck and a Class 8 truck. Again, both come in varying lengths. Most commonly, 48 and 53 ft. trailers are seen, with a power unit which has a wheelbase between 220 and 270 inches (for a sleeper berth tractor). So you'd be looking at between 65 and 77 feet - some combinations are longer, some are shorter - but this is the "norm".
For a sleeper berth equipped truck and a 53 ft. trailer, 70 - 78 feet total length.
An articulated lorry is a truck and trailer - a combination involving a tractor unit and a semi-trailer, known in the United States as a semi-trailer truck.
semi truck, or semi tractor trailer, and 18 wheeler.
That really depends on the length of the trailer itself. It can range anywhere from 32 feet long to over 53 feet.
Trailer is way more bigger than a semi-trailer. Common misconception between a trailer and a semi-trailer. Technically, a trailer has wheels in front and rear and is hitched to a pulling vehicle (car,truck,etc.) A semi- trailer only has wheels in the rear and is hitched to a pulling vehicle (car,truck,etc.)

You call it a semi because it pulls a semi trailer.A semi is a type of trailer. A semi-trailer, as opposed to a full trailer, means it only has axles at the rear of the trailer and a full trailer has axles at the front and rear of the trailer. We call these in the UK "drags", as in wagon and drag, where the wagon that pulls the drag can carry a load on its own, whereas the semi-trailer truck, or tractor unit cannot carry anything without a trailer.
The word semi means half, or part.The tractor and trailer are two parts, hence semi truck and or trailer.
