Answer:
C) 6.15
Explanation:
In a trapezoid, the length of the midsegment is equal to half the sum of the lengths of the two parallel bases.
Given that the two parallel bases of the provided trapezoid measure 4.1 and 8.2, we can calculate the length of the midsegment as follows:

Therefore, the length of the midsegment of the given trapezoid is 6.15 units.
