Answer:

1. Area of the path = 1800 m²

2. The cost of cementing the path = Rs. 360000

Step-by-step explanation:

Dimension of the garden = 90 m by 80 m.

Width of path = 5 m

1. Area of the path = Area of the path with garden - Area of the garden

Area of the garden = length x breadth

                                = 90 x 80

                                = 7200

Area of the garden is 7200 m².

Area of the garden with path = length x breadth

But, length = 90 + 10 = 100 m

      breadth = 80 + 10 = 90 m

Area of the garden with path = 100 x 90

                                                 = 9000

Area of the garden with path = 9000  m²

Area of the path = 9000 - 7200

                           = 1800 m²

2. The cost of cementing the path = Rs.200 x 1800

                                            = Rs. 360000
