Hi, I'm new here. I did physics at uni and I'm writing some physics books. They involve a wide range of maths and hope to ask questions here. My first question however may seem a bit silly but I would appreciate answers. I've included a photo of two rectangles. Could people tell me what they get for the ratio of the widths? And then what they get for the ratio of the lengths? rectangles.JPG

Strange request. I get the ratios of the widths as about 1.08 and lengths as about 1.22, using the pixels as shown. I did not attempt to transform the image to account for the finite perspective and skew (though I did match sides when taking ratios).

Strange request  I know. I've come across this bonkers internet group (like that sort of thing is hard to find ) that are making wild and crazy claims to do with projective geometry. By answering this question you are helping to disprove their nonsense  they wont listen to me.
