Question

Ananya walks three times around a square park of edge 250m. Find the total distance walked by her. 4​

Answer 1

Given : Ananya walks three times around a square park of edge 250m

To find : Total distance covered by her

Solution :

Since Ananya is walking on the boundary of square park, she is covering a distance equals to the perimeter of the square park in one round.

Given that the edge of square park around which Ananya is walking is 250 m. i.e. length of side of square park is 250 m.

We know that perimeter of square is given by, 4 multiply by side.

Perimeter of square park = 4 × Side

Perimeter of square park = 4× 250m

Perimeter of square park = 1,000 m

Ananya covers 1,000m in one round. But we are asked to find the distance covered by her in 3 rounds.

Total distance covered in 3 rounds = 3 × 1,000 m

Total distance covered in 3 rounds = 3,000 m

Or in standard form 3 km, since 1,000 meters is equal to 1 kilometre.

Hence 3,000m is the distance covered by her in 3 rounds.
