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

Step2: Identify base and height

The base of the triangle is $8$ km and the height is $6$ km.

Step3: Substitute values into formula

$A = \frac{1}{2}\times8\times6$.
First, $8\times6 = 48$, then $\frac{1}{2}\times48=24$.
