Question

3. In the given figure, 1 is parallel to BC and D is the mid
point of BC
If area (AABC) = x x area (AEDC),
then the value of x is,
(a) 1 (b) 3 (C) 2 (d) 4​

Answer 1

Answer:

In the given figure, BD=DC as D is the midpoint of BC.

Also △ABC and △EDC have same height as both have base and vertex on parallel lines.

∴ Ratio of areas of both depends on their base i.e BC and DC.

∴x=2 as BC=2×DC
