Step-by-Step Solution
Diagonal BD divides the parallelogram into two congruent triangles, so ar(ABD) = ar(ABCD).
Answer: A)
ABCD is a parallelogram and X is a point on diagonal BD. Lines through X parallel to the sides create smaller parallelograms. By the same-base theorem, ar(triangle ABD) compared with ar(parallelogram ABCD) is:
