Question

The length of the sides of a triangle can be represented as consecutive even integers. If the perimeter of the triangle is 54 cm, what are the lengths of the three sides?

Answer 1

16, 18, 20

Explanation:

Let `x` be the length of the shortest side

`=> x + 2` is the length of the next shortest side

`=> x + 4` is the length of the longest side

---

`x + (x + 2) + (x + 4) = 54`

`=> 3x + 6 = 54`

`=> x = 16`
`=> x + 2 = 18`
`=> x + 4 = 20`
