The perimeter of a triangle is the sum of its sides. So, we have
We have an exact value for the perimeter, and variable expressions for the sides. Let's substitute the formula above with what we're given:
If you divide both sides by 12, you have
So, the lengths of the sides are

Answer: - 2
Step-by-step explanation:
(1/36)^n = 216^n+5
(1/6^2)^n = (6^3)^n+5
(6^-2)^n = (6^3)^n+5
Opening the brackets
6^-2n = 6^3n+15
-2n = 3n + 15
collecting like terms
-2n - 3n = 15
-5n = 15
divide both sides by - 5
n = 15/-5
n = - 3
