(General Math) a. Design, write, compile, and execute a C++ program that calculates and displays the perimeter of a two-dimensional triangle with sides a = 1 in, b = 1.5 in, and c = 2 in, as shown in Figure 2.17. The perimeter is given by this formula:

perimeter = a + b+ c

b. Manually check the values computed by your program. After verifying that your program is working correctly, modify it to determine the perimeter of a two-dimensional triangle with sides a = 1.62 in, b = 2.13 in, and c = 3.2 in.
