In the given figure, DE=BC, DE || BC and the distance between DE and BC is 3 units. D-
4
If BC = 6 units, what is the area of ∆BCE?​

Answer 1

Answer:

∴ the length of the line joining the midpoints of any two sides of a triangle is half of that of the third side. If ∠N = ∠R and ∠M = ∠Q, MN should be parallel to QR because PR and PQ cut MN and QR. ... ∴ If we draw an altitude from E to BC, its length is the same as BD = 3 units.
