python Lab$6$A: Design and implement a program that implements the following $3$ methods:

$-$ Method isValid$(...)$ returns True if the sum of the width and height is greater than $30.$ Otherwise, returns False

isValid$($width$,$ height$)$

$-$ Method area$(...)$ returns the area of the rectangle.

area$($width$,$ height$)$

$-$ Method perimeter$(...)$ returns the perimeter of the rectangle.

perimeter$($width$,$ height$)$

Prompt the user to enter the width and height of a rectangle $($as floats$)$ and use the methods above 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.

Allow the user to re$-$run the program with different inputs using a loop structure. The user input is indicated in bold.

Sample output:

Enter width: $4\mathrm{.}0$

Enter height: $5\mathrm{.}0$

This is an invalid rectangle.

Do you want to enter another width and height $($Y$/$N$)?$: Y

Enter width: $20\mathrm{.}0$

Enter height: $15\mathrm{.}0$

This is a valid rectangle.

The area is: $300\mathrm{.}0$

The perimeter is: $70\mathrm{.}0$

Do you want to enter another width and height $($Y$/$N$)?$: N
