Area of square =Area of the path
therefore 30*30
=900
area of the path is 900square m
cost of labelling it is perimeter of the path *20
perimeter of the path is 900/1=900
length +breadth *2
900+900*2=3600
cost of labelling it is 3600*20=₹72000
therefore 30*30
=900
area of the path is 900square m
cost of labelling it is perimeter of the path *20
perimeter of the path is 900/1=900
length +breadth *2
900+900*2=3600
cost of labelling it is 3600*20=₹72000
