Solution
The correct option is C 7.8 km
Distance walked = 3 x perimeter of square park
Side length of the square park = 650 m
Perimeter of the square park = 4 x Side
⇒ Its perimeter = 4 x 650 = 2600 m
= 2.6 km (since 1 km = 1000m)
Distance covered by the man in 3 rounds
= 3 x 2.6
= 7.8 km
7.8 km
Distance walked = 3 x perimeter of square park
Side length of the square park = 650 m
Perimeter of the square park = 4 x Side
⇒ Its perimeter = 4 x 650 = 2600 m
= 2.6 km (since 1 km = 1000m)
Distance covered by the man in 3 rounds
= 3 x 2.6
= 7.8 km
