    I think b because you suppose to multiple the length and width to get the area

    The area of a rectangle is A = LW We can also write A = WL We are told the length is 7 more than the width, so if the width is w, the length is w + 7. When you multiply the width and length in the formula you get: A = WL A = w(w + 7) Since we are told the area is 60, then we have: w(w + 7) = 60
