Answer:
-22
Step-by-step explanation:

2*3^2 + 2 = 2*9 + 2 = 18 + 2 = 20
Then replace r(3) with 20 to do q(20):
-20-2 = -22

Hi, Ptaverez1! :)
First we must length of an individual square; This can be achieved by using the formula for the area of a square:


Lets input the information we already know:

Take square root.


The length of an individual square tile is
6.5 ft.
Since they're are 9 tiles and the porch in a square, I can conclude that the measurements for the porch are 3 tiles by 3 tiles (as 3*3=9; using the formula for the area of a square.)
Since the length of the porch is 3 tiles, we must multiply the individual tiles piece length by 3:


The formula for the perimeter of a square is:


Lets input the information we know:


The perimeter of the porch is 78 feet²
Hope this helps.
