Distributive property is characterized by the use of parenthesis, wherein you distribute the outside number to each term inside the parenthesis by multiplication. You'll just have to copy the operation inside the parenthesis as it is, whether addition or subtraction. For example,
3(10+4-3) = 3(10) + 3(4) - 3(3) = 33
Since the dimensions are 40 ft by 60 ft, and 16 ft high, I assume the floor of the room is shaped like a rectangle.
Each wall is a rectangle. Two walls measure 40 ft by 16 ft, and two walls measure 60 ft by 16 ft.
lateral area = 40 ft * 16 ft * 2 + 60 ft * 16 ft * 2
lateral area = 1280 ft^2 + 1920 ft^2
lateral area = 3200 ft^2
