Answer:
1 911.484916 square units
Explanation:
Area of the rectangle = 50 * 14 = 700 square units
thanks to the given informations we can find the height of the triangle by using sine.
sin = opposite/hypotenuse
opposite = hypotenuse * sin = 50 * 0,969188 = 48,459397
Area of the triangle = (50 * 48,459397)/2 = 1.211,484916 square units
Total area = 1.211,484916 + 700 = 1.911,484916 square units
