Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_34021 ( "Rank" text, "City" text, "Population" real, "Area (km 2 )" real, "Density (inhabitants/km 2 )" real, "Altitude (mslm)" real )

### Question ###
What is the average area of the city that has a density less than than 206.2 and an altitude of less than 85?

### Accurate SQL ###

SELECT AVG("Area (km 2 )") FROM table_34021 WHERE "Density (inhabitants/km 2 )" < '206.2' AND "Altitude (mslm)" < '85'
