As an alternative to measuring you can use the corrective method of the
transform tool. Either you want to rotate the picture or you want to
modify the perspective. The corrective paradigm for rotation will rotate
the layer/sleection the opposite way you are difining. So if you rotate
the layer boundaries to the shifted scanned image, GIMP will straighten
it out for you. 

You can do the same if the scan has an unwanted "perspective". Using the
corrective paradigm will straighten the image to an ortogonal view.
