Answer 2

Correct question:

How much distance will a boy cover in taking 5 rounds of a square field with side 100 m, state your answer in kilometer.

⇒ The boy covers a distance of 2 km in total.

Explanation:

It is stated that,

It is a square field and the length of each side of the field is 100 m.

∴ Perimeter of the field = (4× side)

                                      = (4×100) m

                                     = 400 m

∴ The distance covered by the boy in each round = The perimeter of the field = 400 m.

Hence,

In 1 round the boy covers a distance of 400 m.

∴ In 5 rounds the boy covers a distance of = (400×5) m

                                                                     = 2000 m.

We know that,

1000 m = 1 km

∴ 2000 m = (2000/1000) km

                = 2 km.

∴ The boy covers a distance of 2 km in 5 rounds around the field.
