Step-by-step explanation:
Area of the path = Area of the park including the path - Area of the park excluding the path.
Let the length and breadth of the park including the path be outer length and outer breadth and the length and breadth of the park excluding the path be inner length and inner breadth.
Inner length =156-10-10=126 m.
Inner breadth=132-10-10=112 m.
Area of the path = 156*132-126*112
=20592-14112=6480 sq. m.
Total cost = Area * Rate
=6480*5=3240 rupees.
