The area of the scale drawing will be: 600 square feet. Step-by-step explanation: The actual length of a wall in the room is 46 feet and the actual width of the room is 69 feet. It is given that: The scale factor of a room for a scale drawing is 2.3. The length of the room according to the scale drawing will be: 46÷2.3=20 feet and the width of the room according to scale drawing will be: 69÷2.3=30 feet We know that the wall is in the shape of a rectangle. This means that the area of scale drawing will be: Length×Width = 20×30 = 600 square feet.
