Why This Is the Correct Answer
The figure gives 28 ft by 24 ft, so the area is 672 sf.
Why the Other Options Are Wrong

616 sf uses a 22 ft width instead of the printed 24 ft.
Option B: 768 sf
768 sf adds 4 ft to the printed length before multiplying.
Option D: 52 sf
52 sf adds length and width instead of multiplying area.
