Answer 1

To find the perimeter \( P \) of an equilateral triangle with side length \( s \), you can use the equation:

\[ P = 3s \]

If the side length \( s \) is 7 m, you can substitute this value into the equation:

\[ P = 3 \times 7 \] \[ P = 21 \text{ m} \]

Thus, the perimeter of the equilateral triangle is 21 m.
