Take a photo of a car outside the building. Measure number of pixels

Hi
Been figuring out how to do this for a while - my solution-
rule - I used 30cm (aka 1 foot), calculator, known length of arm - in my
case .6m, OSM map to measure distance from target.
With hand holding rule vertically measure the target height against the
rule for rule height, this is
