Answer:
48
Step-by-step explanation:
A - B - C - - - D
12 + 12 + 24 = 48
Segment B is midpoint between AC therefore the length between AB is equal to the length between BC. C is midpoint of of AD therefore the length between AB + BC is equal to the length between CD. IF AB is 12 then AB is 12. AC will be 24. Since CD is equal to AD, CD must also be 24. AD is distance AC plus CD = 48.
