Question

a rectangular grassy plot is 75 M long and 60 M broad it has occurred to me or around it on the inside find the area of the park and the cost of constructing it at 125 rupees per metre square

Answer 1

area of plot = 75*60=4500m^2

length of plot including path = 75+2= 77m
breadth of plot including path= 60+2 = 62m
area of plot including path = 77*62 = 4774 m^2

area of path= area of path including road- area of plot 
= 4774-4500
= 274m^2

cost of construction per m^2= ₹125
cost of construction of path = ₹ 125*274
= ₹34250

Answer 2

area of plot = 75*60=4500m² length of plot including path = 75+2= 77m breadth of plot including path= 60+2 = 62m area of plot including path = 77*62 = 4774 m² area of path= area of path including road- area of plot = 4774-4500 = 274m² cost of construction per m²= ₹125 cost of construction of path = ₹ 125*274 = ₹34250
