What is the area of △ABC (in square cm) if AD is the median and area △ADB= 18 square cm?
AD is the median of △ ABC and DE is the median of △ ABD. If area of △ BED = 2.5 sq cm, then the area of △ ABC = ____ sq cm.
IF AD is a median of a triangle ABC, then prove that triangles ADB and ADC are equal in area. If G is the midpoint of median AD, prove that ar (△BGC)=2ar(△AGC).
