Answer 1

Answer:

Rs. 475000

Step-by-step explanation:

outer square                Inner square

 S = 100 m                       s = 100 - 10

                                           =  90 m

Area of path  =  Area of outer square   -  Area of inner square

                     = ( 100 x 100)      -  ( 90 x 90)

                    =   10000   -  8100

                    = 1900 sq.m

Cost of cementing  =  1900 x 250

                                = Rs. 475000
