Lisa ran 3 laps around a square field with an area of 8100square meters how much did she run in kilometers?
:
Find the length of one side of the square
s = sqrt%281800%29
s = 90 m
:
Find the total distance ran, four sides times 3 laps
d = 4 * 90 * 3
d = 1080 meters
Find how many km
1080%2F1000 = 1.08 km
