Question

If the length of the side of a square playground is 78 m. What is the distance covered by an

athlete when he runs 5 rounds around it? Give your answer in km.​

Answer 1

Answer:

78×4= 1560m

1560/1000 = 1.56km

Answer- Athelete covers 1.56km

Answer 2

Answer:

1.56km

Step-by-step explanation:

$side = 78m \\ perimeter \: of \: the \: ground = 4s {}^{2} = 4 \times 78 = 312m \\ total \: distance \: covered \: by \: athlete = 312 \times 5 = 1560m$

$1560m = \frac{1560}{1000} km = 1.56km$
