Airships are a form of aircraft.
An airship has a cabin in which the pilots and passengers travel, and cargo is carried. This is shown in the simplified diagram below.
The floor of the cabin is a rectangle, with a length of 9 m and a width of 2.5 m.
The cockpit occupies an area 1.5 m by 2.5 m at the front of the cabin. This is shown shaded in the diagram below.
The remainder of the floor space is available for passengers and cargo.
Calculate the area available for passengers and cargo, in square metres. (2 marks)
