Hello!
Note that we want to find FEET. First of all, let's convert our inches to feet. There are 12 inches in a foot.
63,360/12=5280
Now we multiply by 3.
5280(3)=15840
Note that if we had divided by 12 and multiplied by 3, we would have been dividing by 4 as well.
63,360/4=15840
Therefore, our answer is D) 15,840.
I hope this helps!
