Answer:

400.5 m

Step-by-step explanation:

To avoid any confusion regarding the width of the track itself affecting the perimeter value, the problem is asking you to find the perimeter of the white inner area only. We know that the straight parts of the track has a total length of 212 m (= 2 x 106 m). If we ignore the straight parts, note that the ends are nothing but two halves of a circle or radius 30m (= 60/2 m) where circumference is

C =2(pi)r = 2(3.14)(30m) = 188.5m

Therefore, the perimeter is

P = 212 + 188.5 = 400.5 m
