Using the dimensions shown for the stabilized construction entrance, what is the plan area?
Correct Answer
D) 588 sf
The figure gives 28 ft by 21 ft, so the area is 588 sf.
Why This Is the Correct Answer
The figure gives 28 ft by 21 ft, so the area is 588 sf.
Why the Other Options Are Wrong

532 sf uses a 19 ft width instead of the printed 21 ft.
Option B: 672 sf
672 sf adds 4 ft to the printed length before multiplying.
Option C: 49 sf
49 sf adds length and width instead of multiplying area.
