CREATE TABLE table_73058 ("Province" TEXT, "Capital" TEXT, "Area  ( km\\u00b2 ) " TEXT, "Population" FLOAT, "Density" FLOAT, "Map region" FLOAT)

when area (km ) is 1605.35, how many provinces are there?
SELECT COUNT("Province") FROM table_73058 WHERE "Area (km\u00b2)" = '1605.35'
SELECT COUNT("Province") FROM "table_73058" WHERE "Area (km\u00b2)" = '1605.35'
