Answer:
Area of a square garden = 2, 500 m².
Length of the side of the garden =  √2,500 = 50 m.
Width of the path = 2.5 m.
Path is inside the garden.
Width of the garden that is inside (enclosed) by the path:
    50 - 2 * 2.5 = 45 m.
Length of the garden inside by the path : Â = 45 m.
So the area of garden inside the path = 45 * 45 m²
   = 2, 025 m².
Area of the path = 2, 500 - 2, 025 Â
  = 475 m².
Cost of laying the path = Rs 25 /m² * 475 m²
  = Rs 11, 875.
