Answer 2

Answer:

Area of oblong field= l×b

Area of oblong field= 49× 36

Area of oblong field= 1764 m²

length of the field excluding the path = 49 -2

length of the field excluding the path = 47m

breadth of the field excluding the path =36 -2

breadth of the field excluding the path =34 m

Area of the field excluding the path = l×b

Area of the field excluding the path =47×34

Area of the field excluding the path = 1598 m²

Area of path = Area of oblong field - Area of the field

excluding path.

Area of path = 1764 -1598

Area of path= 166 m²

cost of constructing the path= 2.50×166

cost of constructing the path= Rs. 415.
