If we take 4 round a field that is 160 long 90 my wide what's is the distance we walk in kilometres

[4 * 2 (160 + 90)] / 1000

To find the distance you walk in kilometers when taking 4 rounds around a field, you need to calculate the total distance covered.

First, find the perimeter of the field:
Perimeter = 2 * (length + width)
Perimeter = 2 * (160 + 90)
Perimeter = 2 * 250
Perimeter = 500 meters

Since you are taking 4 rounds, multiply the perimeter by 4:
Total distance walked = Perimeter * Number of Rounds
Total distance walked = 500 * 4
Total distance walked = 2000 meters

To convert meters to kilometers, divide the total distance by 1000:
Total distance walked in kilometers = 2000 / 1000
Total distance walked in kilometers = 2 kilometers

Therefore, when you take 4 rounds around the field, you walk a distance of 2 kilometers.

To calculate the distance you walk when going around the field, we need to find the perimeter of the field and then multiply it by the number of rounds.

The formula to calculate the perimeter of a rectangular field is P = 2(l + w), where P is the perimeter, l is the length, and w is the width.

In this case, the length (l) of the field is 160 meters and the width (w) is 90 meters. So the perimeter of the field is P = 2(160 + 90) = 2(250) = 500 meters.

Since you mentioned taking 4 rounds around the field, you need to multiply the perimeter by 4. Therefore, the total distance you would walk is 500 meters/round x 4 rounds = 2000 meters.

To convert this distance from meters to kilometers, divide it by 1000, since there are 1000 meters in a kilometer.

So, the total distance you would walk in kilometers is 2000 meters / 1000 = 2 kilometers.
