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.
