Question

Find the length of each side of an equilateral triangle with perimeter 36 inches.Provide your answer below:inches4

Answer 1

$12"$

1) Given that an equilateral triangle has three congruent sides, so we can tell that each side has the following measurement:

$\begin{gathered} P_{\Delta}=l+l+l\Rightarrow P_{\Delta}=3l \\ 3l=36 \\ \frac{3l}{3}=\frac{36}{3} \\ l=12" \end{gathered}$

Note that since they are congruent then we can tell that.
