Let A be the point from where Elton started. Connect points A and C, you get triangle ABC with AB=500 m, BC=350 m and m∠B=100°. Use the cosine rule to determine the length of the segment AC:

Answer:
196.48
Step-by-step explanation:
Area of the semi-circle:
A= (πr^2)/2
A= (3.14 x 64)/2
A= 100.48
Area of triangle:
A= 1/2bh
A= 1/2(16)(12)
A= 96
96 + 100.48= 196.48
