Answer:
60
Step-by-step explanation:
In this case, to find the perimeter, we need to know the value of at least one side.
Since this triangle is equilateral, [tex]5x=24-x[/tex].
Adding x to both sides results in [tex]6x=24[/tex], and subsequently, [tex]x=4.[/tex]
Now that we know x equals 4, we can plug this into either 5x or 24-x and find out that one of the sides is 20.
Equilateral triangles have three equal sides, so 20 times 3, or 60, is the perimeter. I hope this helped!
