You make use of a scale (See Explanation)
Step-by-step explanation:
Given
Length = 12 feet
Required
How would you represent this on drawing.
Knowing that a length of 12 feet can't be drawn on drawing, the best way to do this is to make use of a scale measurement.
The scale to use depends on you and the size of paper at your disposal.
Assume you adopt a scale of 1 inch: 1 feet
This means that a length of 12 feet will be represented by 12 inches in drawings
