Answer:

  168/(x² +7x)

Step-by-step explanation:

The height of each window is 14/(x+7), and the width of each window is 12/x. The area of each window is the product of its height ans width:

  area = (14/(x+7))(12/x) = 168/(x(x +7))

  area = 168/(x² +7x)

Comment on the problem

There is not enough information given to determine suitable values for x. If x is 42, each window is a square 3 3/7 inches on a side.
