Table schema:
CREATE TABLE table_name_28 (length_feet VARCHAR, name VARCHAR, mi_from_kingston VARCHAR, length_meters VARCHAR)

Question: What is Lenth Feet, when Mi From Kingston is greater than 84.5, when Length Meters is greater than 55.5, and when Name is Unnamed?
SQL: SELECT length_feet FROM table_name_28 WHERE mi_from_kingston > 84.5 AND length_meters > 55.5 AND name = "unnamed"
