Question

how much distance will a boy cover in taking 5 rounds of a square field with sides hundred metre state your answering kilometre

Answer 1

Each side is 100m, so perimeter is 400.
So in each round, he'll cover 400m.
In 5 rounds, he'll cover 400m*5 = 2000m or 2km.

Answer 2

as the sides of the square measure 100m
then perimeter of square=4*sides
=>4*100
=>400
and as he took five round of the field then total perimeter..
=>400*5
=>2000m
therefore the distance he covered =2km
