Question: A horse runs around a ground twice and covers a distance of 8 km. One side of square ground is?

---

Solution:

1. Given:

   • Horse covers 8 km in 2 rounds.
   • The ground is square-shaped.

2. Perimeter of square (P) = 4 × side length (s).

3. In one round, distance covered = Perimeter of square = 4 × s.

4. In two rounds:

   $$2 \times (4 \times s) = 8 \, \text{km}$$

   Simplifying:

   $$8s = 8 \, \text{km}$$

5. Divide both sides by 8:

   $$s = 1 \, \text{km}$$

---

Final Answer:

One side of the square ground is 1 km.
