Question

Prove that the line segment joining the mid point of any two sides of a triangle is parallel to the third side and is equal to half of it . In given figure , de =3/4bc , De parallel bc and the distance between dc and bc is 3 units. If bc = 6 units , what is the area of triangle bce? The figure is is a right angle triangle at top A point and at right angle B point and another point is C . A point D at AB is join to E on AC(it seen as parallel) . E point join to point B . Plz answer me
