The perimeter of an equilateral triangle, if side of the triangle is m.
3m
Step 1: In an equilateral triangle, all three sides are equal.
Step 2: Each side is given as \( m \).
Step 3: Perimeter means the total length around the triangle (add all sides).
So,
\( \text{Perimeter} = m + m + m \)
\( \text{Perimeter} = 3 \times m \)
\( \text{Perimeter} = 3m \)
Therefore, the perimeter is \(3m\).
