Question

C is the midpoint of AD. B is the midpoint of AC . BC=12. What is the length of AD

Answer 1

Answer: AD IS 48

Since they have equal length

CD = 2(AB)

AB = BC

BC = 12

Hence, AB = 12

AD = AB + BC + CD

Since, CD = 2(AB)

AD = AB + BC + 2(AB)

AD = 12 + 12 + 2(12)

AD = 24 + 24

AD = 48
