Answer:-
Cost of Construction of the path = Rs 25000.
SOLUTION
Area of rectangle = Length (l) × Breadth(b)
AREA OF RECTANGLE ABCD
Length (l) of the rectangle = 200m.
Breadth (b) of the rectangle = 60m.
Area of the rectangle = 200 × 60
Area of the rectangle = 12000m².
AREA OF THE INNER RECTANGLE.
Length (l) of the rectangle = 200 - (5×2) = 200 - 10 = 190m.
Breadth (b) of the rectangle = 60 - (5×2) = 60 - 10 = 50m.
Area of the rectangle = 190 × 50
Area of the rectangle = 9500 m².
AREA OF THE PATH
Area of the path = Area of Rectangle ABCD - Area of inner rectangle
Area of the path = 12000 - 9500
Area of the path = 2500m².
COST OF CONSTRUCTING THE PATH
Rate of constructing the path = Rs10/m².
Cost of construction = Area of the path × Rate of construction
Cost of construction = 2500 × 10 = Rs25000.
