Answer:

8120 rupees

Step-by-step explanation:

side of square park (A) = 30m

  width of path  = 1m

  side of inner park (a) = 30-1-1 = 28m

  cost of construction = 70 per m^2

 

  Area of path = Area of square park - area of park inside the path  

                       = A^2  -  a^2

                       = 30^2 - 28^2

                       = 900 - 784

                       = 116m^2

 Cost of construction of path  = 70×116

                                               =8120

Answer:

gn, 

   

side of square park (A) = 30m

   width of path  = 1m

   side of inner park (a) = 30-1-1 = 28m

   cost of construction = 70 per m^2

  

   Area of path = Area of square park - area of park inside the path 

                        = A^2  -  a^2

                        = 30^2 - 28^2

                        = 900 - 784

                        = 116m^2

  Cost of construction of path  = 70×116

                                                =8120
