Answer: The length of AB = 8 units
Explanation:
Given: In parallelogram ABCD, Sides A B and D C are parallel.
The length of AB is 4q minus 8 and the length of DC is q + 4.
Since opposite sides of parallelogram is parallel and equal.
So
Length of AB = 4q-8=4(4)-8=16-8=8 units
Hnece, the length of AB = 8 units
