Find the area of a triangle with a base of 23 kilometers and a height of 12 kilometers.(1 point)
The area of the triangle is square kilometers.
The area of a triangle is calculated using the formula: Area = 1/2 * base * height.
Given that the base is 23 kilometers and the height is 12 kilometers:
Area = 1/2 * 23 km * 12 km
Area = 1/2 * 276 km^2
Area = 138 km^2
Therefore, the area of the triangle is 138 square kilometers.
