    C 304 Correct Answer Incorrect Answer
    D 240 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the width of the rectangle = тАШxтАЩ metres Then, length of the rectangle = (x + 3) metres Perimeter of the rectangle = 2 ├Ч (length + width) Or, 2 ├Ч (x + x + 3) = 50 Or, 2x + 2x + 6 = 50 Or, 4x = 50 тАУ 6 = 44 Or, x = 44/4 = 11 m So, area of the rectangle = x ├Ч (x + 3) = 11 ├Ч 14 = 154 m2
