Scale Diagrams
When we use details about a real-world object/building/location to draw an accruate representation.
Skills needed for this topic: - Convert metric measurements - Identify and apply a given scale
Click on the image begin.
Scale Diagrams
It is important we read all of the information before we begin planning our scale diagram.
First we have to establish a scale. The amount of space available to us dictates the scale we can use.
1cm
1 : 50
Click on the image to move on.
The line above is 1cm. When we write a scale, we use the format 1 : 50. This tells us that 1cm on the image is 50cm in real life.
Scale Diagrams
Now we have a scale we can apply the conditions within the question. We can now convert given measurements (m) into cm and draw the perimeter of the garden.

1cm
1 : 50
Scale Diagrams
Click on the on the graph paper below to draw the line.
1cm
1 : 50
Scale Diagrams
This line is 550cm long. 550cm ÷ 50cm = 11.
1cm
1 : 50
Scale Diagrams
This line is also 550cm long. 550cm ÷ 50cm = 11.
1cm
1 : 50
Scale Diagrams
This line is 400cm long. 400cm ÷ 50cm = 8.
1cm
1 : 50
Scale Diagrams
This line is 250cm long. 250cm ÷ 50cm = 5.
1cm
1 : 50
Scale Diagrams
The length of this line is not defined on the diagram. However, we can use the previous line as the end point horizontally.
1cm
1 : 50
Scale Diagrams
The length of this line is also not defined on the diagram. However, we can draw a line to close the shape and complete the garden. horizontally.
Click on the greenhouse to continue.

Scale Diagrams
The instructions state the greenhouse must be positioned in the top right hand corner of the garden, and must be a 50cm space between the greenhouse and the edge of the garden.
