The distance around the rectangular field can be calculated using the formula:
distance = 2(length + width)
In this case, the length is 100 meters and the width is 97 meters. So the distance around the field is:
distance = 2(100 + 97) = 2(197) = 394 meters
Since you run 3 laps around the field, the total distance you run is:
total distance = 3 × distance around the field
total distance = 3 × 394 meters
total distance = 1182 meters
Therefore, you run 1182 meters in total.
