A square shaped ground is 20 meter long. If a person takes 5 rounds of the ground, how much total distance does he cover?

500 m

360 m

400 m

None of these

Step 1: Calculate the perimeter of the square ground.

The perimeter of a square is given by P = 4 × side length. Here, the side length is 20 meters.

P = 4 × 20 = 80 meters

Step 2: Calculate the total distance covered in 5 rounds.

Total distance = Number of rounds × Perimeter

Total distance = 5 × 80 = 400 meters
