distance measurements from image to world

please look at the attached image... If i have the 2 red distances in meters( real distances- height of the building) and have also the 2 distances in the image [pixels](with the 3 vanishing points' coordinates - one of them is the intersection point of the 2 blue lines ) is there any way to measure the distance of the blue line (building width in meters)? i also have the coordnates of the vie point( gps coordinates from where the image was taken) thanks in advance

I don't think there is a specialized function or toolbox in Matlab to solve your question. However you can have the distance of the blue line in world by solving a geometric problem, which is shown in the image.
