Sorry, I can't quite measure it from here. I guess you'll have to get a ruler and measure it yourself.

3 inches to the nearest inch and 3 inches to the nearest half inch both refer to a length not less than 2.5 inches and less than 3.5 inches. 3 inches to the nearest quarter inch refers to a length not less than 2.75 inches and less than 3.25 inches.
draw a quadrangle measure the sides to the nearest half inch writ the length next to each side .find the perimeter
None of them since a thread has a finite length and finite width. A point has neither length nor width whereas a line, line segment and ray do not have any width. A plane has infinite length and width. The nearest approximation is a line segment.

Yes, of course, you lose more precision if you round to a half inch. Try rounding 0.76 to the nearest half unit, and to the nearest quarter unit, and see what happens.
