Madhya Pradesh Police Exam Model Paper 7

Given:
Side of square garden = 350 m
Formula Used:
Perimeter of square = 4 x side
Total distance covered = Number of rounds × Distance covered in 1 round
Calculation:
⇒ Perimeter of garden = Perimeter of square = 4 x side
$\Rightarrow 4\times 350\mathit{m}=1400\mathit{m}$
⇒ Distance covered by him in 5 rounds = Numbers of rounds × Distance covered in 1 round
$\Rightarrow 5\times 1400\mathit{m}=7000\mathit{m}$
$1000\mathit{m}=1\mathit{k}\mathit{m}$
$\Rightarrow 7000\mathit{m}=7\mathit{k}\mathit{m}$
∴ He will cover 7 km in 5 rounds of the garden.
The correct option is 3 i.e. 7 km.
