Answer:
You can call the static method using the following statement:
double area = Area.calcAreaSquare(3.5);
Explanation:
In Java, a static method can be called by directly using the Area class name and followed with a dot syntax as shown above. This will invoke the calcAreaSquare() method and act on the input 3.5 and return the output to the variable area.
Calling a static method doesn't need to go through a class instance.
