Hi,

I want to join a contest but the instructions they've given are faulty(I'm not talking about this particular sentence)!!! I need help understanding the following statement because the whole program is ready except for this part...

Here it is:

".........The length of mail is always the side parallel to the written address............................. the length plus the distance around the other sides of a package equals 84 inches or less."

what does the underlined statement mean?
