Решение:
Сторона:
a = c·
= 5.65685·
= 5.65685·
= 5.65685·0.366
= 2.07
Сторона:
b = c·
= 5.65685·
= 5.65685·
= 5.65685·1.225
= 6.93
Периметр:
P = a + b + c
= 2.07 + 6.93 + 5.65685
= 14.66
Площадь:
p =
S =√p·(p-a)·(p-b)·(p-c)
=√7.328·(7.328-2.07)·(7.328-6.93)·(7.328-5.65685)
=√7.328 · 5.258 · 0.398 · 1.67115
=√25.627400014445
= 5.062
