conjugation of avere and regular '-are' verbs

Is the formal form of you not the same as 2nd person plural in Italian? The reason I ask is that the grammar books show the '-are' verbs ending in '-ate' for 2nd person plural but the formal form for you seems to end in ' -a' as in 'Parla inglese?' Similarly with avere - the books show 'avete' but the formal You have is 'Ha' as in 'Ha una camera'? How do you ask 'What is your name' in the polite/formal form? Is it 'Come Lei chiama'?

Mi scusi. I have found the answer in another grammar book. Lei is used with 3rd person singular ending.

hi Alice, it's correct. Please note that the pronoun "voi" was used as formal form many years ago especially when a young person was speaking to an aged person. In some part of Italy it may be still used. Ciao
