Question

In a triangle ABC, AD and AE are median and altitude on BC respectively, perimeter of triangle
ABC is equal to: [AD = 2root 7 . AE = 2root 6 & BC = 6
​

Answer 1

Answer:

Correct option is A)

ABC is the triangle and O the centroid. Let AO produced meet BC in D. The Area of the triangles ABD = Area of triangle ACD.

(Reason CD=BD and same altitude and Area =

2

1

×base×altitude)

Similarly, Area EBD = Area ECD. Subtracting i.e

Area ABD - Area EBD = Area ACD - Area ECD which implies Area ABE = Area ACE
