Answer:
398.21 m
Step-by-step explanation:
The field inside a running track is made of a rectangle that is 84.39 m long and 73 m wide to gather with a half circle at each end.
So, the radius of each half circle will be [tex]\frac{73}{2} = 36.5[/tex] m.
Therefore, the total distance around the track i.e perimeter of the area covered by the track will be = 2 × Perimeter of each half circle + 2 × Length of the rectangle.
= Perimeter of full circle + 2 × Length of the rectangle.
= [tex]2\pi r + 2l[/tex]
= [tex]\frac{2 \times 22 \times 36.5}{7} +2 \times 84.39[/tex]
= 398.21 m.(Answer)
