While you are waiting for a reply on dimesions you could practice your own estimation skills. We all have to start with the best reference we can find and then go from there. In this thread there is a great direct top-side view of an Eagle sitting in the middle of the pad. If your model has a known length of 22" you could measure the length of the Eagle in the image, the length would be "equal to" 22 inches in proportion. You can then measure the length of the pad and do the math to calculate the pad length in relationship to the 22". You can repeat that for all the details you want to know. The good thing about this image is that the Eagle and the Pad are close together so you can largely ignore any distorsion from "prespective". If you need to "make" a lot of measuements from the image you can also make a simple "proportional ruler". You know the "length" of 22" so if you put in 22 division, each will be 1", Divide that length as many times as you want to get half inch, quarter inch, eighth inch, etc. Personally I convert things to centimeters-millimeters, as I find it easier to work with and make fewer errors when I need to add and subtract lengths.
I thought I needed to add, the "proportional ruler" would only be good for the one image you did the original calculations on. However, if you have another image and you can find identical "features" in both images you can use the "measured" length in the first to find the {proportional length in the second, and make a second ruler that can be used on the second image.
Another approach when you have multiple images and the appropriate software, is that you can resize each the images so that the same feature in each image is the same length. Then your proportional ruler will work equally well on all the resized images. The software will probably allow you to directly measure the size of construction lines on the images. However not everyone has the software, time, and money for that approach. Making simple paper ruler(s) is low tech but very workable.
