$\huge \dag \: { \boxed{ \underline{ \sf{ \pink{Answer}}}}}$

given ,

length of the big square = 100 m

length of the small square = 5 m

Side of the smaller square = Side of the bigger square - 2(width of the path)

                                         

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 100 - 2(5)\\  = 90 m$

Area of the path =

$\sf( 100)² - (90)² = 10000 - 8100 = 1900 sq m$

Cost of cementing at the rate of Rs 250 per 10 m² = 250 x 190 = Rs 47500
