Question

What type of measuring device would u use to measure the girth of a tree?

Simplest way would be with a dressmaker's (plastic or fabric) measuring tape. A builder's (metal) measuring tape is not flexible enough. Alternatively, use a rope to encircle the girth then lay it straight and measure with a ruler.

Explanation:

Another alternative: if the trunk is cylindrical, measure the diameter and multiply by `pi`.
