I’m not sure the notion of “THE load address” makes sense. It may be valid for your specific case, but not in general. ELF files can have multiple load sections, each of which has a load address.
Normally I would say: look in the program headers. Each header of type LOAD describes something that’s loaded, and it shows the addresses.
