Answer:
GH is 5 unit.
Step-by-step explanation:
Given,
C is the midpoint of Segment AB,
D is the midpoint of Segment AC,
E is the midpoint of Segment AD,
F is the midpoint of Segment ED,
G is the midpoint of Segment EF,
H is the midpoint of Segment DB,
Given, DC = 40 unit,
⇒ AD = 40 unit, ( From equation (1) )
⇒ ED = = 20 unit, ( From (2) )
⇒ EF = = 10 unit, ( From (3) )
⇒ GF = = 5 unit ( From (4) )
