30 is the value of P
Steps:
A perfect square follows the pattern
Answer:
The scale factor is 4
Step-by-step explanation:
This question requires an attachment; I'll answer this question using the attached figure
From the attachment
<em>Length OA = 3 units</em>
<em>Length OA' = 3 units + 9 units</em>
<em>Length OA' = 12 units </em>
<em></em>
Scale Factor is calculated as follows;

Given that the original shape is ABC, the original side will be OA
Hence, Original Side = 3 units
New Side = OA' = 12 units
The formula becomes


<em>Hence, the scale factor is 4</em>

Remember, diameter = 2 x radius
14 meters = 140 decimeters and 15 meters=150 decimeters and so on
