Design and implement program that implements the following 3 methods: - Method isValid(...) returns true if the sum of the width and height is greater than 30 boolean isValid(double width, double height){) - Method Area (...) returns the area of the rectangle if it is a valid rectangle .3B double Area (double width, double height){} Method Perimeter(...) returns the perimeter of the rectangle if it is a valid rectangle double Perimeter(double width, double height){} Always remember that in Java and C#, the methods must be public and static The main method should prompt the user to enter the width and height of a rectangle (double values) and uses the methods to print out a message followed by the area and perimeter if the rectangle is valid. Otherwise, it prints out only the message " This is an invalid rectangle." Note: that method isValid(...) is used to validate the input before attempting to compute the area and perimeter.

![Design and implement program that implements the following 3 methods:
- Method isValid(...) returns true if the sum of the width and height is greater than 30
boolean isValid(double width, double height){}
- Method Area (...) returns the area of the rectangle if it is a valid rectangle
%3
double Area (double width, double height){}
- Method Perimeter(...) returns the perimeter of the rectangle if it is a valid rectangle
double Perimeter(double width, double height){}
Always remember that in Java and C#, the methods must be public and static
The main method should prompt the user to enter the width and height of a rectangle (double values)
and uses the methods to print out a message followed by the area and perimeter if the rectangle is
valid. Otherwise, it prints out only the message “ This is an invalid rectangle."

Note: that method isValid ( ...) is used to validate the input before attempting to compute the area
and perimeter.
Design the main method in the test program such that it allows the user to re-run the program
with different inputs (using a sentinel loop structure).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa4ccd380-5631-4b45-a670-c967a981a240%2Faf2f2ca1-4da1-4820-b625-68ae9f136d1a%2F7ngcu3l_processed.jpeg&w=3840&q=75)
