Using the dimensions shown for the base plate, what is the plan area?
Correct Answer
D) 420 sf
The figure gives 28 ft by 15 ft, so the area is 420 sf.
Why This Is the Correct Answer
The figure gives 28 ft by 15 ft, so the area is 420 sf.
Why the Other Options Are Wrong
Option A: 364 sf
364 sf uses a 13 ft width instead of the printed 15 ft.
Option B: 480 sf
480 sf adds 4 ft to the printed length before multiplying.
Option C: 43 sf
43 sf adds length and width instead of multiplying area.
Memory Technique
Printed-edge rule for base plate: dimensions make the area; scale does not.
Reference Hint
