What is a suitable scale for a closed traverse having the following distances in meters: 10,000, 6,000, 2,000, 1,500, 900?

A suitable scale for a closed traverse with distances of 10,000m, 6,000m, 2,000m, 1,500m, and 900m would depend on the size of the paper you are using to draw the traverse.

If you are using a standard size paper (e.g. A4), you could use a scale of 1:10,000 or 1:5,000 to ensure that the traverse fits on the paper while still being legible.

Alternatively, if you are using a larger paper size, you could use a scale of 1:20,000 or 1:25,000 to show the traverse in more detail.

Ultimately, the scale you choose should allow you to accurately represent the traverse while also fitting it onto the paper you are using.
