Description This program will determine the usable area of a house. The rooms are rectangular in shape and maximum of four rooms are allowed to be calculated at once. It will use the area formula for a rectangle to find the usable area of each room and once the calculation are made for each room it will print out the total usable area of a house to the output screen. Analysis This program will calculate the usable area in square feet of a house with a maximum of four rooms that are rectangular
