Final answer:
The segment bisector dividing AB into two equal parts at 5.5 units is correct, resulting in the total length of AB being 11 units.
Step-by-step explanation:
The question you are working on appears to be a mathematics problem dealing with the concept of a segment bisector. A segment bisector is a point, line, ray, or other segment that divides a line segment into two equal parts. If you identified the segment bisector as 5.5, this means you're suggesting that it divides the segment AB into two segments of equal length, which would be 5.5 units each.
Given this interpretation, if AB is bisected by a point at 5.5 units from A, then the whole length of AB would be twice the length of one of its halves, making AB equal to 11 units. Therefore, the segment bisector correctly divides the segment into two equal parts of 5.5 units, and the full length of segment AB would indeed be 11 units.
