First, we will multiply 5 by 28 to find out the total number of ages in the room.
5 * 28 = 140
Now, we will multiply 6 by 29 to find out the total number of ages in the room after the new person comes in.
6 * 29 = 174
Now, in order for us to find the age of the new person, then we will subtract 140 from 174.
174 - 140 = 34
So, the person that entered the room is 34 years old.
