Since, area of rectangle = 105 square inches.
Area of rectangle with length 'l' and width 'w' is given by the formula =

It is given that the width of the rectangle is 14 inches.
We have to determine the length of the rectangle.
Let 'x' be the length of the given rectangle.
So, area of rectangle =


So, x = 7.5 inches
Therefore, the length of the rectangle is 7.5 inches.
