Below is the java code for the ladtract class :-

public class ladtract

{

private double length;  //length of tractor

private double width;   //width of tractor

public double calculateArea(){  

    return length*width;    //calculate and return the area of the tractor

}

public boolean equals(Object o) {

    if (o == this) {    //check if it's the same object

        return true;

    }

       if(o.length==this.length && o.width==this.width){   //check if the length and width are same for both objects

           return true;

       }

       return false;  

}

public String toString(){

    return "Area="+calculateArea(); //return the area of the tractor as a string

}

}
