      Question

      The cost of fencing a rectangular plot at the rate of

      Rs. 12/metre is Rs. 960. If the ratio of the length to breadth is 5:3, find the area of the rectangular plot.
      A 400 sq m Correct Answer Incorrect Answer
      B 375 sq m Correct Answer Incorrect Answer
      C 350 sq m Correct Answer Incorrect Answer
      D 300 sq m Correct Answer Incorrect Answer

      Solution

      Let the length and breadth be 5x metres and 3x metres respectively.
      According to the question,
      2 Γ— (5x + 3x) = 960 / 12
      Or, 2 Γ— 8x = 80
      Or, 16x = 80
      Or, x = 5 metres
      Therefore, area of the rectangular plot = 5x Γ— 3x = 15xΒ² = 15 Γ— 25 = 375 mΒ²
