Step-by-Step Solution
Triangle DEC has base DC; E lies on AB, the parallel to DC. So triangle DEC and parallelogram ABCD share base DC between the same parallels, giving ar(DEC) = ar(ABCD).
Answer: A)
ABCD is a parallelogram. E is a point on AB. ar(triangle DEC) compared with ar(parallelogram ABCD):
Hint: DC is the base, and E lies on AB which is parallel to DC.
