Distance = 7 km 800 m = 7800 m Perimeter × 3 = 7800

2 (x + 330) = 2600
⇒ x + 330 = 1300
⇒ x = 1300 – 330 = 970m

To find the length of the ground, we need to calculate the total distance Raju runs in three rounds and then subtract the width of the ground from this total distance.

Given:
Distance covered by Raju in one round = 7 km 800 m
Width of the ground = 330 m

Calculating distance covered in three rounds:
Distance covered in one round = 7 km 800 m = 7800 m
Distance covered in three rounds = 3 * 7800 m = 23400 m

Subtracting the width of the ground from the total distance:
Length of the ground = Total distance covered - Width of the ground
= 23400 m - 330 m
= 23070 m

Therefore, the length of the ground is 23070 m.

Hence, the correct answer is option D) 970 m.
