Question

the length of a rectangle field is 72mby 58keya walks around it at the rate of 3km per hour how long will she take to make 3round

Answer 1

Hi friend,

Here is your answer,
_____________________________________________________________

Length of rectangle = 72 m

Breadth of rectangle = 58 m

Perimeter of the field = 2*(l+b)
                                  = 2*(72+58)
                                  = 2*130
                                  = 230 m

Total distance keya walks = 3*230
                                         = 690 m
                                         = 0.69 km

Speed = 3km/h

Time = distance/speed = 0.69/3
                                     = 0.23 hours
                                     = 0.23 * 60
                                     = 13.8 minutes
