the diagonals of a rhombus are 6 m and 8 m long. What is the perimeter of this rhombus?

To find the perimeter of the rhombus, we can use the fact that the diagonals of a rhombus bisect each other at right angles. Given that the diagonals are 6 m and 8 m, we can treat each half of these diagonals as the legs of a right triangle, with the side of the rhombus as the hypotenuse.

### Step-by-Step Solution:

1. The diagonals are 6 m and 8 m, so each half of the diagonals will be:
   \[
   \frac{6}{2} = 3 \text{ m} \quad \text{and} \quad \frac{8}{2} = 4 \text{ m}
   \]

2. Each side of the rhombus forms the hypotenuse of a right triangle with legs of 3 m and 4 m. Using the Pythagorean theorem:
   \[
   s = \sqrt{3^2 + 4^2} = \sqrt{9 + 16} = \sqrt{25} = 5 \text{ m}
   \]

3. Since all four sides of a rhombus are equal, the perimeter \( P \) is:
   \[
   P = 4 \times s = 4 \times 5 = 20 \text{ m}
   \]

### Answer:
The perimeter of the rhombus is **20 meters**.
