1) Since point M is the midpoint of segment AB, segment AM will be equal to segment MB. Therefore, AB = 4.3 dm.

2) The total length of the segment AB will be equal to the sum of the segments AM and MB.

AB = AM + MB = 4.3 + 4.3 = 8.6 dm.

3) Since 1 dm = 10 cm = 100 mm, then 8.6 dm = 8.6 * 100 mm = 860 mm.

Answer: The length of the segment AB is 860 millimeters.
