Singles Doubles
The court is 23 ⋅ 8 metres long.
Its width is 8 ⋅ 2 metres for singles matches and 10 ⋅ 9 metres for doubles matches. The service line is 6 ⋅ 4 metres from the net. Use the parallel and perpendicular line constructions to draw a scale model of the court as shown. Indicate the scale used on the diagram.
