this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
