The program below display the following menu:Geometry Calculator1. Calculate the Area of a Circle2. Calculate the Area of a Rectangle3. Calculate the Area of a Triangle4. Quit
Enter your choice (1-4):If the user enters 1, the program should ask for the radius of the circle and then display its area. Use 3.14159 for . If the user enters 2, the program should ask for the length and width of the rectangle, and then display the rectangle’s area. If the user enters 3, the pro- gram should ask for the length of the triangle’s base and its height, and then display its area. If the user enters 4, the program should end.
Input Validation: Display an error message if the user enters a number outside the range of 1 through 4 when selecting an item from the menu. Do not accept negative values for the circle’s radius, the rectangle’s length or width, or the triangle’s base or height.
You are therefore, required to complete the program by putting in codes under each comment.include…

Write a program that displays the following menu:
Geometry Calculator
1. Calculate the Area of a Circle
2. Calculate the Area of a Rectangle
3. Calculate the Area of a Triangle
4. Quit
Enter your choice (1-4).
If the user enters 1, the program should ask for the radius of the circle and then display its area. Use the following formula to calculate the circle's area:
area = pi * r ** 2
Use 3.114159 for pi and the radius of the circle for r. If the user enters 2, the program should ask for the length and width of the rectangle, and then display the rectangle, and then display the rectangle's area. Use the following formula to calculate the rectangle's area:
area = length x width
If the user enters 3, the program should ask for the length the tringle's base and its height, and then display its area. Use the following formula to calculate the area of the triangle:
area = basse x height x .5
If the user enters 4, the program should end.

Write a program for The Carefree Resort named ResortPrices that prompts the user to enter the number of days for a resort stay. Then display the price per night and the total price. Nightly rates are $200 for one or two nights; $180 for three or four nights; $160 for five, six, or seven nights; and $145 for eight nights or more.arrow_forwardFat Percentage Calculator One gram of fat has 9 calories. If you know the number of fat grams in a particular food, you can use the following formula to calculate the number of calories that come from fat in that food: Calories from fat = Fat grams × 9 If you know the food’s total calories, you can use the following formula to calculate the percentage of calories from fat: Percentage of calories from fat = Calories from fat ÷ Total calories Create an application that allows the user to enter: • The total number of calories for a food item • The number of fat grams in that food item The application should calculate and display: • The number of calories from fat • The percentage of calories that come from fat Also, the application’s form should have a CheckBox that the user can check if he or she wants to know whether the food is considered low fat. (If the calories from fat are less than 30% of the total calories of the food, the food is considered low fat.)
