Math problem on scale factor for room dimensions

[From: ] [author: ] [Date: 12-06-07] [Hit: ]
--I know the answer is 15 cm by 4.5 cm, but could someone explain how to get that?so, for every 200cm in reality we have 3cm on the blueprint.Room length is 10 m = 1000cm => 1000/200 = 5.......
Amber spent a day with a design engineer. A blueprint that the engineer was working on uses a scale of 3:200. If the room dimensions are 10 m by 3 m, what lengths would be drawn on the blueprint in the centimetres?

THANKS:)

3cm : 200cm (2 metres)

so, for every 200cm in reality we have 3cm on the blueprint.

Room length is 10 m = 1000cm => 1000/200 = 5......so, 5 x 3cm = 15cm

Room width is 3 m = 300cm => 300/200 = 1.5......so, 1.5 x 3cm = 4.5cm
