      Question

      The length of a rectangle is 3 metres more than its

      width. If the perimeter of the rectangle is 70 metres then what is the area (in m2 ) of the rectangle?
      A 150 Correct Answer Incorrect Answer
      B 216 Correct Answer Incorrect Answer
      C 304 Correct Answer Incorrect Answer
      D 136 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      Let the width of the rectangle = ‘x’ metres Then, length of the rectangle = (x + 3) metres Perimeter of the rectangle = 2 × (length + width) Or, 2 × (x + x + 3) = 70 Or, 2x + 2x + 6 = 70 Or, 4x = 70 – 6 = 64 Or, x = 64/4 = 16 m So, area of the rectangle = x × (x + 3) = 16 × 19 = 304 m2
