Answer» Let the length and breadth of the field be ‘l’ m and ‘B’ m respectively. According to the question, the length of the field is 3 m more than twice the breadth ⇒ l = (2b + 3) m We KNOW that, PERIMETER of a rectangular field = 2(l + b) ⇒ 84 = 2(2b + 3 + b) ⇒ 84/2 = 3b + 3 ⇒ b = 39/3 = 13 m ∴ b = 13 m l = 2b + 3 = 2 × 13 + 3 = 29 m ∴ l = 29 m |
