Correct Answer
B) 756 sf

Why This Is the Correct Answer
The rectangular mat area is length multiplied by width.
Why the Other Options Are Wrong
Option A: 120 sf
Choice A adds 42 ft and 18 ft, then doubles the sum instead of multiplying for area.
Option C: 840 sf
Choice C uses 20 ft as the width instead of the shown 18 ft dimension.
Option D: 1,512 sf
Choice D doubles the single crane-mat area.
