Answer:
14
Explanation:
Find the diagram of the parallelogram attached
According to the parallelogram shown, M is the midpoint of length of diagonal AC and BD.
If E is the midpoint of AC, then AE = EC and AE + EC = AC
Given AE + EC = AC
Substituting AE = EC into the formula, it becomes;
AE+AE = AC
2AE = AC
AE = AC/2
Given the length of side AC = 28;
AE = 28/2
AE = 14
Hence the measure of length AE is 14
