    Question

    Each side of square ‘A’ is 6 cm less than that of

    square ‘B’. The perimeter of a rectangle is 4 times the difference of the perimeters of the two square. If the length of the rectangle is 28 cm, then find its breadth.
    A 23 cm Correct Answer Incorrect Answer
    B 20 cm Correct Answer Incorrect Answer
    C 21 cm Correct Answer Incorrect Answer
    D 28 cm Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let each side of the square ‘A’ be ‘a’ cm Therefore, each side of square ‘B’ = (a + 6) cm Difference between their perimeters = 4(a + 6) – 4a = 24 cm Therefore, perimeter of the rectangle = 4 × 24 = 96 cm Let the breadth of the rectangle be ‘b’ cm According to the question, 2 × (28 + b) = 96 Or, 28 + b = 48 Or, b = 20 cm
