(i) In a given figure, BE is a median of △ ABD. If the area of parallelogram ABCD is 24 cm2. Then the area of △ BDE is:
(ii) In the above diagram if AD = 12 cm then find the value of AE.

Solution
(i)In a parallelogram, triangle between the same parallels and on the same base have area which is equal to the half of that of parallelogram.
So, area of △ ABD =12× area of ABCD
BE is a median
Area of △BDE=12× area of △ ABD (Median divides the triangle into 2 equal areas)
