/*Write a program for a lawn-mowing service. The lawn-mowing season lasts 20 weeks. The weekly fee for mowing a lot under 400 square feet is $25. 

The fee for a lot that is 400 square feet or more, but under 600 square feet, is $35 per week. 

The fee for a lot that is 600 square feet or over is $50 per week. 

Prompt the user for the length and width of a lawn, and then display the weekly mowing fee, as well as the total fee for the 20-week season.

Use TryParse() method to handle user input and validation.
