A mile is not a measure of an area so, as asked, the question has no answer. Unfortunately, 150 km squared is ambiguous since it could refer to an area of 150 square kilometres (say 10 km by 15 km) OR an area of the square with sides of 150 km. 150 square km = 57.92 square miles 150 km square = 22500 square km = 8687.3 sq miles = 93.21 miles square.
