Question

Ali runs along the sides of a square park whose side is 10 m long. Find the distance covered by Ali if he runs around the park twice.

• A. 40 m
• B. 60 m
• C. 80 m
• D. 100 m

Answer 1

The correct option is C

80 m

Given: Side of the Square = 10 m
Ali 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 $\times$ 10 m
= 40 m
Distance covered by Ali in two rounds of the park = 2 $\times$ Perimeter of the park
= 2 $\times$ 40 m
= 80 m
Therefore, distance covered by Ali is 80 m.
