As its one significant figure you are looking at the first number and the second number. If the second number is greater than 5 then you round the first number up and vice versa. In this case there is an eight, which is bigger than 5 obviously so you round the first number to get 40000.

The only way I can envision this is put all 4 points on 1 line segment. They go in the order of ADCB. I can only draw it this one way.
Given
D is the midpoint of AC
C is the midpoint of DB
AC = 3 cm
Argument
AC = 3 cm Given
AD = DC D is the midpoint of AC
AD = 3/2 Definition of a midpoint.
DC = 3/2 Definition of a midpoint
DC = 3/2 Last statement
DC + CB = 1.5 + 1.5. C is the midpoint of BD
DB = 3 Consolidation of equals
AD + DB = AB
1.5 + 3 = 4.5 Substitution.
