Some scales are more appropriate than others. Why would there be no point using a scale of 1cm : 2m if you wanted to represent a building that is 160m long and 140m wide? Can you suggest a more suitable scale to represent this building?


It’s important to choose a scale that is appropriate to both the length and the width.


2. Draw scaled representations of these playgrounds in your copy. Choose a scale that you think is appropriate. Remember to write the scale under the rectangles.


Playground 1 Length – 27m Width – 21m


Playground 4 Length – 60m Width – 50m


Playground 2 Length – 18m Width – 12m


Playground 5 Length – 88m Width – 32m


Playground 3 Length – 35m Width – 28m


Playground 6 Length – 54m Width – 45m


Farmer Ted is planning to put a fence around his field. To plan it properly, he needs to know the exact length and width of his field. This is a scaled picture of his field.


5cm 3cm


Scale 1cm : 4.9m


What is the actual length and width of this field? Length = 5cm


Width = 3cm


Scale = 1cm : 4.9m Scale = 1cm : 4.9m


Actual length = 5 × 4.9m = ? Actual width = 3 × 4.9m = ?


142 Length
