Write a method that accepts an array containing an even number of integers. Each pair of integers indicates the dimensions (in feet) of a room in an office. The area of each of these rooms can be found by finding the product of the dimensions since each room is rectangular. Return the total area of the office indicated by the array of room dimensions. For example: {8, 10, 12, 20} indicates an office with an 8 by 10 room (80 square feet) and a 12 by 20 room (240 square feet). The total area of this office is 320 square feet, so you would return 320.
