Write a Python Code for the following example:

Write a class named "LandParcel" with constructor method included. The class should accept three attributes at object initiation: length, width, and unit cost. Define three more methods in the class to calculate the perimeter, area, and total cost of the plot. Afterwards, instantiate an object, call the required methods, and display the length, width, and total cost on the screen. Use proper naming convention and formatting.
