Determine the message length from the following hex viewer record:

Explanation:
In hex records, the length of a message is often stored as a 16-bit value written in hex. To find the length, read the two bytes in order and treat them as a single hex word. The two bytes shown for the length are 81 and 0D, which together form 0x810D. That hex value is the message length. If you convert to decimal, 0x810D equals 33037, but the representation here is in hex, so 810D is the correct length value. The other options don’t match the two-byte hex length field that this record uses.
