Assuming you could even create a big enough ruler (you can't), a ruler is going to be a really poor method of accurately measuring such large distances. For a start, you'd need to ensure it is perfectly perpendicular to the earth, and that there is no flexing. Also, you're going to have to find a material that is capable of withstanding what I would imagine are immense pressures at the earth end, and definitely at the sun's end. Also, it needs to not expand as temperature increases. Furthermore, you need to accurately measure it and mark it before you can use it. Factor in the time it takes to make the measurement, coupled with the distance between the earth and the sun constantly changing, and I'd say the time you should waste thinking about making a giant ruler should be equal to the time I've wasted making this post.
