from math import sqrt
lines = input()
a, b, c = map(int, lines.split())
def compute(a, b, c):
circumferences = a + b + c
# 海伦公式
s = circumferences / 2
areas = sqrt(s * (s - a) * (s - b) * (s - c))
return circumferences, areas
circumference, area = compute(a, b, c)
print(f"{circumference=:.2f} {area=:.2f}")
