BC=2*DE ( by mid point theorem)
nazirabano:
answer is wrong answer will be 6.4 CM
what is wrong here the formula which is written is correct
yes u also correct
In ∆ABC , D and E are the midpoints of sides AB and AC . DE = 1/2 BC (by midpoint theorem.) therefore, 3.2 = 1/2 × BC . Therefore , BC = 3.2 × 2 = 6.4 cm.
these is the right answer.
ok

AD=DB,AE=EC
IT MEANS D&E ARE MID POINTS
SO,
BY MID POINT THEOREM
DE=1/2BC
2DE=BC
2(3.2)=BC
6.4 CM=BC
