Very Hard Quantitative Comparisons Geometry Comparisons

In a parallelogram ABCD, the adjacent sides are given lengths where side AB is 10 units and side AD is 6 units.

A diagonal AC divides the parallelogram into two triangles, triangle ABC and triangle ADC.

Figure A: The area of triangle ABC.

Figure B: The area of triangle ADC.

Which figure has the greater area?

Figure A has a greater area than Figure B.

Figure B has a greater area than Figure A.

Both figures have the same area.

The area cannot be determined without knowing angles.
