# In the triangle A In ΔABC, as F is midpoint of AB and E is midpoint of AC, we apply the theorem:-

The line segment joining the midpoints of two side of a triangle is parallel to the third side and equal to half of it, we get and EF||BC

Similarly, In ΔOBC, as P is midpoint of BG and Q is midpoint of GC, we apply the theorem:-

The line segment joining the midpoints of two side of a triangle is parallel to the third side and equal to half of it, we get and PQ||BC

BC = 2× PQ

BC = 2 × 3

BC = 6 cm

The length of BC is 6 cm.
