So if Area = Length x width then you substitute (width+7) for Length in the equation what would the equation look like?

They just ask for the area of the suitcase. Area = length*width
The length is 7 inches longer than the width.

Let w be the width. Length will be (w + 7)

A = w(w+7)

144 = w(w+7), solve for w. The width of the suitcase
