Answer:
- <u><em>All real numbers except c = 0 and c = 3.</em></u>
Explanation:
The equation is:

Since c - 3, c, and c(c - 3) are he denominators, none of them can be equal to zero:
- c (c - 3) ≠ 0 ⇒ c ≠ 0 and c ≠ 3.
Now you can multiply both sides of the equation by the common denominator: c (c - 3):

That means the equality is valid for all real numbers for which it is defined, which is all real numbers except c = 0 and c = 3.
Wait are you looking for area perimeter or was there another question? the area would be 42^2ft, and the perimeter would be 29 ft
