Calculate and output the wall's area. (2 pts)Note: This zyLab outputs a newline after each user-input prompt. For convenience in the examples below, the user's inputvalue is shown on the next line, but such values don't actually appear as output when the program runs.Enter wall height (feet):12.0Enter wall width (feet):15.0Wallarea:180.00 square feet(2) Extend to also calculate and output the amount of paint in gallons needed to paint the wall.

6. A palindrome is a number or text phrase that reads the same backwards or forwards. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554 and 11611. Write a program that reads a 5 digit integer and determines whether it is a palindrome. Hint: One way to do this is to use division (/) and modulus (%) operators to separate the number into individual digits.
