| 28 inches is 7/4 the width of the rectangle.

Find the width by dividing 28 by 7/4, we get:

28 / (7/4) = 28 * 4/7 = 16 dm – the width of the rectangle.

Formula for the perimeter of a rectangle:

P = 2 (a + b). P – perimeter, a – length, b – width.

P = 2 (28 + 16) = 2 * 44 = 88 dm.

Answer: The perimeter of the rectangle is 88 dm.
