Rs. 4/metre is Rs. 360. If the length of the field is 13 metres more than its breadth, then find the length of the rectangular field.Solution
Let the length of the rectangular field be ‘l’ m Breadth of the rectangular field = (l – 13) m Therefore, perimeter of the rectangular field = 2 ×(l + l – 13) = (4l – 26) m According to the question, 4l – 26 = 360/4 Or, 4l = 90 + 26 Or, l = 116/4 = 29 metres
