Question

The sides of a scalene triangle have measures that are consecutive even integers. If the perimeter of this

triangle is 60 inches, what is the length of the longest side of the triangle?

Answer 1

Answer: 22

Explanation:

Let the sides have lengths
`x-4, x-2, x`. Since the perimeter is 60,

`x-4+x-2+x=60\\\\3x-6=60\\\\3x=66\\\\x=22`

So, the length of the longest side is 22 units.
