Draw a neat diagram of a badminton court with all its specifications.

A correct drawing shows a rectangular badminton court 13.40 m long and 6.10 m wide for doubles (5.18 m wide for singles), with the net 1.55 m high at the posts. It shows: 1. The centre line dividing the court into the right and left service courts. 2. The short service line 1.98 m from the net on each side. 3. The long service line for singles at the back boundary line, and for doubles 0.76 m inside the back boundary line. 4. The side lines for singles and doubles, and the back boundary line.
