Question

Rectangular windows are being made into a wall of windows for an office building. Each wall is 14 feet tall and 12 feet wide. The wall will be divided into x columns and into x + 7 rows. Find the area of one of these windows.

Answer 1

168/(x² +7x)

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.
