Distribute:
(12n-12)5
60n-60 = A(n)
You can't really find what n is I don't think, because you have 2 unknown variables n and A(n).
Answer: Man sorry I don’t know how to solve that go to a math solver or something

<h3>
Answer: 128.74 square meters</h3>
=========================================================
Explanation:
The area of the garden only (ignore the circular pathway) is approximately
A = pi*r^2
A = 3.14*20^2
A = 1256
The area of the garden plus the path is approximately
A = pi*r^2
A = 3.14*21^2
A = 1384.74
Notie how I added on 1 meter to increase the radius to 21
Subtract the two circle areas to get the area of the circular ring.
1384.74 - 1256 = 128.74
The units for all of the areas mentioned are "square meters".
