A Paint Company has asked you to write an application that calculates the quantity and price of Paint required to a paint for rectangular rooms in a building.

To calculate the quantity of paint required, you have to first calculate area of room, assuming one gallon is enough for 120 square feet.
Then for price you multiply the quantity of paint by the price per gallon. For example, the area of room that is 34 square feet. To cover that room with paint that costs 1000 per gallon would cost (1/120*34=2.83 gallon, 2.83*1000=2833rs).(you can take help from internet for exact formulas)
First, you should create a class named RoomDimension that has two attributes: one for the length of the room and one for the width. The RoomDimension class should have a member function that returns the area of the room.

Once you have written the class, use them in an application that asks the user to first enter total number of rooms, create a dynamic array, then ask user to enter the dimensions of a rooms in array and the price per gallon of the paint. The application should display the total cost of the paint for each room in array.
