    A 75 Correct Answer Incorrect Answer
    B 70 Correct Answer Incorrect Answer
    C 65 Correct Answer Incorrect Answer
    D 85 Correct Answer Incorrect Answer

    Solution

    Let the breadth of the rectangle = x, so the length of the rectangle = 3x Perimeter = 2(l + b) 40 = 2(x + 3x) 20 = 4x x = 5 Breadth = 5 m, Length = 15 m So the area of the rectangle = 5 × 15 = 75 m2
