The 'A' frame is actually the part at the front of the caravan where the hitch is located so I think you are referring to the actual awning rail length. If you have a look at the link below it shows where the measurement should be taken but if you have already done this then you need to convert from feet to inches so 31 feet converted to centimetres is 945 so looking at the grid size you would need a size 12 in the Dorema range. Don't quote sizes though as different awning manufacturers will often use different sizing structures so it may be a different size in an Isabella or Bradcot for example.
