The perimeter of the 20th figure is 80
What is the perimeter of the 20th figure?
from the question, we have the following parameters that can be used in our computation:
The figure
From the figure, we have the perimeter of the n-th figure to be
Perimeter = 4 * Number of position
Using the above as a guide, we have the following:
Perimeter = 4 * 20
Evaluate
Perimeter = 80
Hence, the perimeter of the 20th figure is 80
