Question

    The length of the rectangle is triple its breadth. If

    the perimeter of the rectangle is 56 m, then find the area (in m2) of the rectangle.
    A 137 Correct Answer Incorrect Answer
    B 117 Correct Answer Incorrect Answer
    C 147 Correct Answer Incorrect Answer
    D 127 Correct Answer Incorrect Answer

    Solution

    Let the breadth of the rectangle = x, so the length of the rectangle = 3x Perimeter = 2(l + b) 56 = 2(x + 3x) 28 = 4x x = 7 Breadth = 7 m, Length = 21 m So the area of the rectangle = 7 × 21 = 147 m2
