Answer:
Total length of running track is 371.24 m .
Step-by-step explanation:
Total running track = Running track around straight region + running track around curved region.
Running track around straight region = 2 × length of straight region
= 2×82 m
= 164 m
Running track around curved region = 2 × length of curved region
= 2 × π × radius of curved region
= 2 × 3.14 × 33 m
= 207.24 m
Therefore , total length of running track = 164 + 207.24 m
= 371.24 m
