Write a C++ program that inputs the length and width of two rectangles (in integers) representing a house and a garage. Write a function that uses Call-by- Value int rectArea (int len, int wid) that returns the area of a rectangle with length len and width wid. Divide the area of the garage by the area of the house and multiply by 100 to determine the percentage (int). Enter your name as a Global variable and all other variables should be local variables in main or rectArea. Area = length*width Percentage = 100* GarageArea/HouseArea Sample Input Length of House (ft): 50 Width of House (ft): 60 Length of Garage (ft): 10 Width of Garage (ft):20
