    A 182 Correct Answer Incorrect Answer
    B 122 Correct Answer Incorrect Answer
    C 172 Correct Answer Incorrect Answer
    D 192 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the breadth of the rectangle = x, so the length of the rectangle = 3x Perimeter = 2(l + b) 64 = 2(x + 3x) 32 = 4x x = 8 Breadth = 8 m, Length = 24 m So the area of the rectangle = 8 × 24 = 192 m2
