#7 Using the engineering problem-solving methodology, write down the detailed 5 steps that are applied for developing a C++ program that computes the area A of a rectangle with sides a and b. The program should prompt the user to enter the sides. (Recall that A a .b). 15 8 Create a complete C++ source code for computing the area A of a rectangle with sides a and b. The program should prompt the user to enter the sides. (Recall that A = ab) 20 (Include comments in your program) 9 (Not required, bonus credit) Identify and correct the errors in the following statement Double 2mile (2); cout >> "2 mile = " >> 2mile >>
