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
