Explanation:
Read the length and width of lawn from user with the help of scanner object. Find the area of the lawn.If the area if less than 400 then Weekly mowing fee is $25 and find the 20-week seasonal fee by multiply 25 with 20.If the area is greater than 400 and less than 600 then Weekly fee is $35 and seasonal fee will be 35*20.if the area is greater than 600 then Weekly fee is $50 and seasonal fee will be 50*20.
Output:
Enter length of lawn:15
Enter width of lawn:12
Weekly mowing fee is:$25
20-week seasonal fee is:$500
