I heard second leg was 10m longer
All legs in 4x100/4x200/4x400 are equal in length from exchange zone to exchange zone, the difference where one leg can be longer than others is in where you hand off. For example, if you have off early in the zone from leg 1 to 2, and late from leg 2 to 3, it can be even 20m longer for leg 2 and 10m shorter for legs 1 and 3. Given this, the longest potential leg in the relays is always either the #2 or #3 leg.
