Решение:
Сторона:
a = c·
= 28.8·
= 28.8·
= 28.8·0.8165
= 23.52
Сторона:
b = c·
= 28.8·
= 28.8·
= 28.8·1.115
= 32.11
Периметр:
P = a + b + c
= 23.52 + 32.11 + 28.8
= 84.43
Площадь:
p =
S =√p·(p-a)·(p-b)·(p-c)
=√42.22·(42.22-23.52)·(42.22-32.11)·(42.22-28.8)
=√42.22 · 18.7 · 10.11 · 13.42
=√107118.2593668
= 327.29
