Question

6 km (with a square figure having side length 6 km)

Explanation:

Step1: Identify the shape and formula

The figure is a square. The formula for the area of a square is \( A = s^2 \), where \( s \) is the side length.

Step2: Substitute the side length

Given \( s = 6 \) km, substitute into the formula: \( A = 6^2 \).

Step3: Calculate the result

\( 6^2 = 36 \) square kilometers.

Answer:

The area of the square is \( 36 \) square kilometers.
