Designing a scaled plan |  |
For the rich task you will be designing your own school yard. For your presentation you will need to able to create your own scaled plan of your design. The tasks below are to remind you of how draw a plan and to ensure it is the correct scale. |
Converting measurements: In the example below, we see how to work out "real life" measurements from a plan.
 | On the left is the plan for a room. The scale for this plan is 1 : 200. This means that 1 cm on the plan represents 200 cm (or 2 m) in real life.
To work out the dimensions of the room in real life, we need to measure the room on the plan: The room measures 3 cm long by 2 cm wide. Because the scale is 1 : 200, the real life measurements will be 200 times larger. The length of the room in real life must therefore be 3 cm × 200 = 600 cm or 6 m. The width of the room in real life must be 2 cm × 200 = 400 cm or 4 m |
Perimeters and Areas When working out perimeters and areas, it is best to convert to the "real life" measurements first, and then do the calculations. In the plan above, we worked out that the "real life" dimensions of the room were 6 m by 4 m. The perimeter of this room must be 6 m + 4 m + 6 m + 4 m = 20 m.
The area of this room must be 6 m × 4 m = 24 m². |  |
