Explanation
Given information
The scale of the drawing was 5inches to 1 yard
The first thing to do is to convert the inches to yard for unit consistency
According to the Standard International Unit, 1 yard = 36 inches
Let x represents the length in the yard
Therefore, 5 inches = 36 inches
In real life drawing, 5 inches is equivalent to 5 inches
Recall that, the scaling factor is the ratio of the larger figure to the smaller figure
The scaling factor is 5 : 36
