Przekątne rombu mają 6 i 6 pierwiastków z 3 . Oblicz: a) pole b) obwód c) długość wysokości
d1 = 6
d2 = 6√3
a)
P = 1/2 * d1 * d2 = 1/2 * 6 * 6√3 = 18√3
b)
(1/2d1)² + (1/2d2)² = a²
a² = 3² + (3√3)²
a² = 9 + 27
a² = 36
a = 6 ------- bok rombu
Ob = 4 * a = 4 * 6 = 24
c)
P = a * h
18√3 = 6 * h
h = 18√3 / 6
h = 3√3
