Question

The area of square feild is 132.25km square.if a man runs around the field three times, what is the distance travelled by him

Answer 1

let the side of square field be x

area of square field is = side^2

132.25 = x^2

therefore by taking square roots on both side

11.5 = x

therefore the perimeter of square field is 11.5 kilometre

if a man runs around the field three times then the distance travelled by him will be

11.5 × 3 = 34.5

therefore the man travels 34.5 km
