Have you considered using ImageJ https://imagej.nih.gov/ij/
Slightly different result, it will be due to the Gimp selection.
Change the image convert to binary, check the histogram
looks like https://i.imgur.com/SUOu8Wu.jpg
---------------
edit: In fact that might be the way to go in GIMP
'Colors -> Threshold` to make the image binary
Then in the histogram move the slider over to the left
Gives the number and percentage straight off. https://i.imgur.com/z9Tauju.jpg
