Answer: 16.2 km
Explanation:
The height of the triangle can be found using the area formula for triangles:
Area = (1/2) × base × height
Rearranging the formula to solve for the height gives:
height = (2 × Area) / base
In this case, the area of the triangle is 64.8 km² and the base is given as 8 km. So, the height of the triangle can be calculated as:
height = (2 × 64.8 km²) / 8 km
height = 16.2 km
