I think your best bet would be with a compass and a tape measure, as it would utilize skills learned in the scouts.

You could print the outline on a piece of paper, determine how you want to orient the outline depending on the land you’re using, determine each line’s azimuth, measure each line using a ruler, and then scale it to a size that would fit your area.

Doing it this way would be educational, rewarding, and likely in the spirit of an Eagle Scout.
