$2.$Write a C$++$ program that does the following:

a$.$Create a C$++$ file with the name problem$2.$cpp$.$

b$.$Declare two variables to store the width and height of a letter$-$size $(8\mathrm{.}5$ x $11$ inches$)$ sheet of paper.

c$.$Compute and print the area $($width times height$)$ of the sheet of paper.

d$.$Compute and print the perimeter $($two times width plus two times height$)$ of the sheet of paper.

Sample run of the program:

The area of a letter$-$size sheet of paper is $93\mathrm{.}5$

The perimeter of a letter$-$size sheet of paper is $39$
