Answer:
The answer to your question is 287.52 u²
Step-by-step explanation:
To calculate the area of a triangle it is necessary to have the base and the high of this figure.
Base = 35 km
height = ?
To calculate the height draw a right triangle and use the trigonometric function sin to find it.
sin Ф = [tex]\frac{opposite side}{hypotenuse}[/tex]
Opposite side = hypotenuse x sinФ
Opposite side = height = 37 x sin28
= 16.43 km
Calculate the area
Area = (1/2)(35)(16.43)
Area = 287.52 u²
