Why This Is the Correct Answer
The figure gives 36 ft by 21 ft, so the area is 756 sf.
Why the Other Options Are Wrong
Option A: 684 sf
684 sf uses a 19 ft width instead of the printed 21 ft.
Option B: 840 sf
840 sf adds 4 ft to the printed length before multiplying.
Option D: 57 sf
57 sf adds length and width instead of multiplying area.
