Question

A man runs along the sides of a square park whose side is 13 m long. How much distance will the man cover if he runs around the park three times?

• A. 155 m.
• B. 156 m.
• C. 157 m.
• D. 158 m.

Answer 1

The correct option is B 156 m.

Given:
Side of the Square = 13 m

Man is running along the boundary of the park.

This implies that the distance covered by him will be equal to the perimeter of the park.

Perimeter of a square = 4 $\times$ Side

$\Rightarrow$ Perimeter of the square park
= 4 $\times$ 13 m
= 52 m
Distance covered by man in three rounds of the park
= 3 $\times$ Perimeter of the park
= 3 $\times$ 52 m
= 156 m

Therefore, distance covered by man is 156 m.
