Lorraine wants to the paint the 4 rectangular walls of a room, including the door. The room is 14 feet long and 14 feet wide, and the walls are 10 feet high. What is the total area that is to be painted?
The base of the room is a 14 x 14 square, and the walls are 10 feet high, that means the 4 rectangular walls are congruent, with height 10, and width 14. Thus the total area of the 4 rectangular walls is 10 x 14 x 4 = 40 x 14 = 560 feet squared.
