In the given figure P and Q are the midpoints of sides AB and AC
respectively of ∆. Also D and E are the mid points of AP and AQ
respectively if DE = 2.3 cm, then find the length of BC.

Answer:
Length of BC = 9.2 cm
Step-by-step explanation:
All the triangles are similar .
Hence , ∆ABC ~ ∆APQ ~ ∆ADE
Now , by Thales theorum , we have
DE : PQ = 2 : 1
Hence , PQ = 2DE = 2 * 2.3 = 4.6 cm
Similarily , BC = 2PQ = 2 * 4.6 = 9.2 cm
Hence , BC = 9.2 cm
Glad to help you ;)
