the length of a rectangular garden is 5 on4 times its breadth the expenditure for 4 LED wiring around the garden at rupees
Answers
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.)
