Here is the answer of the given statement above. The lengths from shortest to longest would be in this order: 28 dm, 30,277 cm,  629,00 mm then 1.2 km. The shortest would be 28 dm and the longest is 1.2 km. In order to get this, i converted all the measurements into a uniform unit in order to easily compare. Hope this answer helps. Thanks for posting your question.

Answer:

28 dm, 30277 cm, 629000 mm, 1.2 km

Explanation:

Convert all the lengths to a single unit.

Let us convert them to m

1 dm = 0.1 m

28 dm = 2.8 m

1 mm = 0.001 m

629000 mm = 629 m

1 km = 1000 m

1.2 km = 1200 m

1 cm = 0.01 m

30277 cm = 302.77 m

So, arranging them from shortest to longest we get

2.8 m, 302.77 m, 629 m, 1200 m

or

28 dm, 30277 cm, 629000 mm, 1.2 km
