    C 253 Correct Answer Incorrect Answer
    D 243 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) 72 = 2(x + 3x) 36 = 4x x = 9 Breadth = 9 m, Length = 27 m So the area of the rectangle = 9 × 27 = 243 m2
