Question

the triangle below has a perimeter of 27 cm. what is the length of one side of the triangle? all 3 sides are the same length.

Explanation:

Step1: Recall perimeter formula

Perimeter of an equilateral triangle $P = 3s$, where $s$ is side - length.

Step2: Solve for side - length

Given $P = 27$ cm, we have $s=\frac{P}{3}$. Substituting $P = 27$ into the formula, we get $s=\frac{27}{3}$.

Answer:

9 cm
