To calculate the area of triangle A, we need to first calculate the length of its base and height. The base is the distance between points B and C, which is 6 kilometers. To find the height, we can draw a perpendicular line from point A to line BC. This perpendicular line intersects BC at point D, which is 2 kilometers from point C. Therefore, the height of triangle A is 2 kilometers.
Area of triangle = (base × height) / 2 = (6 km × 2 km) / 2 = 6 km²
Now we need to convert km² to million square meters. Since 1 km² = 1 million square meters, the area of triangle A in million square meters is 6 million square meters.
Therefore, the best choice is C, which is 3.15 million.
