Question

Find the perimeter of an equilateral triangle whose each side measures $12cm$.

Answer 1

Step 1 - Given, an equilateral triangle with each side = $12cm$

Step 2 - Perimeter of an equilateral triangle will be the sum of all three sides and in an equilateral triangle, all sides are equal. Hence, all sides are of length $=12cm$

Step 3 - Perimeter of triangle = Sum of all three sides

$$\begin{gathered} =12+12+12 \\ =36cm \end{gathered}$$
