               Answers:

                                2
               1. (i) 150000 m

               (ii) ₹ 1500000000

               2. Breadth = 40 m
               3. Area of the rectangle = 880cm   2


               Area of square = 961cm    2

               Square shaped wire encloses more area.

               4. Cost of whit washing area = ₹ 284
