A rectangular plo

Answer :

The Area of the rectangle = l × b


The total area of the rectangle = 40 × 16 = 640 m2


Length of inside rectangle = 40 - 2(2) = 36 m


Breadth of inside rectangle = 16 - 2(2) = 12m


Area of inside rectangle = 36 × 12 = 432 m2


Area of road = 640 – 432 = 208 m2


Cost of paving = 15 × 208 = Rs. 3120


Cost of grass = 9 × 432 = Rs. 3888
