Question:
The perimeter of an equilateral triangle is 9n - 12. Write an expression to represent the length of each side.
Solution:
- The perimeter of an equilateral triangle is 9n - 12.
- We know, perimeter of a triangle is the sum of the three sides of the triangle.
- Also, in an equilateral triangle, all the sides are equal.
- Therefore, the length of each side of the triangle
[tex] = \frac{9n-12}{3} \\ = \frac{3(3n - 4)}{3} \\ = 3n - 4[/tex]
Answer:
The length of each side of the triangle is 3n-4.
Hope it helps!!
