Question

Each side of a square field is 70 m70 cm. How much distance will a boy walk in order make one complete round of this field?

Answer 1

Given
Each side of a square field $=70m$
Distance covered to complete one round of the field by the boy is equal to the perimeter of the field
Hence, the perimeter of square field can be calculated as below :
Perimeter $4\times side$
$=4\times 70m$
We get,
$280m$
Therefore, the distance covered by the boy to complete one round of the field is $28m$
