C. Drawing Scale Diagrams of 2-D shapes

How would you draw a scale diagram when a scale factor is given?


Example 1

A rectangular pool has dimensions 25 metres by 15 metres.

Draw a scale diagram of this pool with a scale factor of .

Centimetres will be easier to work with, so begin by converting the dimensions of the pool to centimetres.

25 m = 2500 cm 15 m = 1500 cm

The scale diagram dimensions are 12.5 cm by 7.5 cm.

Draw a rectangle with dimensions 12.5 cm by 7.5 cm.
