A piece of wire is to be bent in the form of a rectangle to put around a picture frame. The length of the picture frame is 1.5 times the width. Write a program that prompts the user to input the length of the wire and outputs the length and width of the picture frame.
The screen size of a TV is given by the length of the rectangular diagonal.
Traditional TVs come in 4:3 ratio, that is, the ratio of length to width is 4 to 3. This means, if the length is x inches, then the width is (3/4)x.
LCD TVs come in 16:9 ratio.
Instructions
Write a program that:
Prompts the user to input the length of the diagonal (in inches) of the screen
Allows the user to select which type of TV the user would like to view the dimensions for
Ex.1: Traditional TV area. 2: LCD TV Area 3: Both types of TVs area
Have the program calculate and display the:
Screen length
Screen width
Screen area
for the specified type of TV.
Suppose two line segments intersect. The two endpointsfor the first line segment are (x1, y1) and (x2, y2) and for the second line segment are (x3, y3) and (x4, y4). Write a program that prompts the user to enter these four endpoints and displays the intersecting point.

- A piece of wire is to be bent in the form of a circle to put around a picture frame. Write a program that prompts the user to input: The length of the wire The program then outputs: the radius and area of the circle. You may assume that π = 3.1416. Declare PI as a named constant with this valuearrow_forwardWrite a program that prompts the user to input an integer between 1 and 36. If the number is less than or equal to 10, the program should output the number; otherwise, it should output A for 11, B for 12, C for 13, . . . , and Z for 36.arrow_forwardProcedure 2. Write a program that takes the x-y coordinates of a point in the Cartesian plane and prints a message telling either an axis on which the point lies or the quadrant in which it is found. If x or y is 0, the code will print out "The point is on x or y axis". For example, if your input x is 2.5, and y is 1, it will print out "The point is in Quadrant One"; if the input x is -2.3, and y is -3.2, it will print out "The point is in Quadrant Three"; if the input x is 0, and y is 20, it will print out "The point is on x or y axis ". Requirements: 1. The inputs of x and y should be float data type. 2. The input should prompt a message on the screen to ask for the input x and y.arrow_forward
- A county collects property taxes on the assessment value of property, which is 60 percent of the property’s actual value. If an acre of land is valued at $10,000, its assessment value is $6,000. The property tax is then 75¢ for each $100 of the assessment value. The tax for the acre assessed at $6,000 will be $45. Write a program that asks for the actual value of a piece of property and displays the assessment value and property tax.arrow_forwardAirline companies apply baggage restrictions for their passengers. An airline company has decided to apply a 10kg limitation for passengers' hand luggage and 20kg for their normal baggage. When passengers arrive, they enter their hand and normal luggage weight from the keyboard. If passengers exceed their normal baggage allowance of 10 dollars per gram, they pay 12 dollars per kg. Accordingly, write the program that calculates the baggage price of the airline they will go to according to the baggage values entered by the arriving passenger and keeps this from closing the program for each passenger. Note: If hand and normal baggage allowances are stretched below the maximum value, the payment amount will be considered not negative. An example printout is given on the right.
