Answer» Given :- The LENGTH of a rectangular garden is 5/4 times its breadth. The expenditure for four layered wiring around the garden at Rs.36 per meter is Rs.1,29,600. What is the breadth of the garden ? SOLUTION :- Let us assume that, Breadth of the rectangular garden is x m . so, → Length of rectangular garden = (5/4) of x = (5x/4) m . then, → Perimeter of rectangular garden = 2(Length + Breadth) = 2{(5x/4) + x} = 2{(5x + 4X)/4} = 2(9x/4) = (9x/2) m. therefore, → Perimeter od layering wire 4 times = 4 * (9x/2) = 18x m. hence, → 18x = (Total cost/Rate) → 18x = (129600/36) → 18x * 36 = 129600 → 648x = 129600 → x = 200 m (Ans.)
