Explanation:

Step1: Recall triangle area formula

The area formula for a triangle is $A=\frac{1}{2}\times base\times height$.

Step2: Identify base and height

The base of the shaded - triangle is $4$ km and the height is $6$ km.

Step3: Calculate the area

Substitute the values into the formula: $A = \frac{1}{2}\times4\times6$. First, $4\times6 = 24$, then $\frac{1}{2}\times24=12$.

Answer:

$12$ square kilometers
