Final answer:
The area of the parallelogram is 327.2 km².
Step-by-step explanation:
To find the area of a parallelogram, you need to multiply the base by the height. In this case, the base is 24.6 km and the height is 13.3 km. So, the area can be calculated as:
Area = Base x Height
Area = 24.6 km x 13.3 km
Area = 326.58 km²
Rounding to the nearest tenth, the area of the parallelogram is 327.2 km², which is closest to option d. 327.18 km².
