Step-by-step explanation:the curved part must come in 15 m on each end, leaving a straight length of only 20 m for the rectangle.

outer area = rectangle of 20by30 + 1whole circle of radius 15

= 600 + π(225)

= (225π + 600) m^2

inner area = 25by20 + π(12.5^2)

= 500 + 156.25π

track area = 100 + 68.75π
