Datos:
a = 38 m
b = 54 m
α= 67° 30` =67,0083°
α/2 = 33,50°
Calculemos la altura:
sen67,0083° = h/a
0,92* 38m = h
h = 34,96 m
Diagonal mayor: aplicamos Teorema de coseno:
D² = a² + b² -2ac*cosα/2
D² = (38m)² +(54m)² -2(38m* 54m)* cos33,50°
D = √1444m² + 2916m² - 3422,74m²
D = 30,61 m
Diagonal menor: Ley del paralelogramo:
2(a² +b²) = D² + d²
d = √2 (a² + b²) -D²
d = √2 [ (38m)² +(54m)²] - (30,61m)²
d = √2 (1444m² + 2916m²) - 936,97m²
d = 58,50 m
Área:
A = b* h
A = 54 m * 34,96m
A = 1887,84 m²
