The area of a triangle can be calculated using the formula: A = 1/2 * base * height. Using the Pythagorean theorem, we can find that the length of BC is approximately 0.390 km. Since triangle ABC is a right triangle with AC as the hypotenuse, the height of the triangle is equal to the length of BC. Thus, the area of triangle ABC is approximately 0.5 * 0.390 km * 0.320 km = 0.0624 km^2, which rounds to 0.125 km^2 to three significant digits.
