I don’t understand what you mean
The legs are 10 and 14 both squared 100+196 =296 find the square root of it = to 17.2
Swimming half way around implies half of the circumference.
Circumference = pi x diameter
C = pi x 20
C = 20pi
20pi / 2 = 10pi
You swam 10pi meters = 31.42 meters.
Hope this helps!! :)
