Решение:
Сторона:
a = c·
= 37.2·
= 37.2·
= 37.2·1.225
= 45.57
Сторона:
b = c·
= 37.2·
= 37.2·
= 37.2·1.366
= 50.82
Периметр:
P = a + b + c
= 45.57 + 50.82 + 37.2
= 133.59
Площадь:
p =
S =√p·(p-a)·(p-b)·(p-c)
=√66.8·(66.8-45.57)·(66.8-50.82)·(66.8-37.2)
=√66.8 · 21.23 · 15.98 · 29.6
=√670802.917312
= 819.03
