If you make a cultural communication misstep, the best thing to do is to:
a. avoid causing more harm by pretending that nothing happened.
b. explain the policy that justifies your actions.
c. file a report to document the incident.
d. apologize and express a willingness to learn.

a, b, c - sides of a triangle

a + b > c

a + c > b

b + c > a

we have a = 5m and b = 11m. substitute:

5 + 11 > c

16 > c → c < 16

5 + c > 11         subtract 5 from both sides

c > 6

11 + c > 5         subtract 11 from both sides

c > -6

c < 16 and c > 6 and c > -6

thereofre your answer is 6m < c < 16m

if this is true of false i think it would be true
