Near Ted’s house, there is a circular park. In this park, there are rectangular and circular paths with width 1.5 m. The rectangular paths pass through center of the park. The local community decided to put grass beds on entire pathway. The inner radius of the circular path is 8 m. If the distance between any of the gates and the circular path is 2.5 m, find the cost of putting grass beds on the entire pathway at 0.1 paise per square cm.
