Question

the area of square field is 34.225km².if a man runs around the field three times,what is the distance covered by him?step by step explaination​

Answer 1

Answer:

70.32 km

Step-by-step explanation:

Given,

    area of square field = 34.225 km²

We know ,

      area of a square = s² (s = side)

             34.225  =  s²

                  s   =  √34.225

                ∴s = 5.86 km

Now ,  

           Perimeter of a square = 4s

                                                = 4 ×5.86

                                                =23.44 km

             No. of rounds = 3

               ∴Total distance covered = perimeter × 3

                                                         = 23.44 × 3

                                                        = 70.32 km
