    C 1200 Correct Answer Incorrect Answer
    D 1350 Correct Answer Incorrect Answer

    Solution

    Let the breadth of the rectangle = x, so the length of the rectangle = 3x Perimeter = 2(l + b) 160 = 2(x + 3x) 80 = 4x x = 20 Breadth = 20 m, Length = 60 m So the area of the rectangle = 20 × 60 = 1200 m2
