Where are the boxes we’re looking at??
Yes it is because none out the inputs have the same outputs
Area=width*length. Let width=x ft, then length=3x ft, given the information in the problem. The area of basement=x*3x=768, 3x^2=768, x^2=256, x=16. The width is 16 feet. Therefore, length=3x=3*16=48 feet.
The question isn’t clear, post the question so I could help :) !
