One of the properties of an equilateral triangle is that all the sides are equal

From the statement given, each of the lengths of the triangle is at most 9 feet long means that each of the lengths is less than or equal to 9 feet

This can be represented mathematically as


\begin{gathered} l\leq9ft \\ \text{Where l is the length} \end{gathered}

The perimeter of an equilateral triangle is the addition of the three equal lengths i.e.


l+l+l=\text{ 3l}

If x represents the perimeter, then
