Question

    The length of the rectangle is triple its breadth. If the perimeter of the rectangle is 120 m, then find the area (in m 2) of the rectangle.

    A 685 sq.m Correct Answer Incorrect Answer
    B 635 sq.m Correct Answer Incorrect Answer
    C 675 sq.m Correct Answer Incorrect Answer
    D 655 sq.m 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) 120 = 2(x + 3x) 60 = 4x x = 15 Breadth = 15 m, Length = 45 m So the area of the rectangle = 15 × 45 = 675 m2
