    Question

    Each side of square β€˜A’ is 4 cm less than that of

    square β€˜B’. The perimeter of a rectangle is 3 times the difference of the perimeters of the two square. If the length of the rectangle is 15 cm, then find its breadth.
    A 9 cm Correct Answer Incorrect Answer
    B 8 cm Correct Answer Incorrect Answer
    C 10 cm Correct Answer Incorrect Answer
    D 12 cm Correct Answer Incorrect Answer

    Solution

    Let each side of the square β€˜A’ be β€˜a’ cm Therefore, each side of square β€˜B’ = (a + 4) cm Difference between their perimeters = 4(a + 4) – 4a = 16 cm Therefore, perimeter of the rectangle = 3 Γ— 16 = 48 cm Let the breadth of the rectangle be β€˜b’ cm According to the question, 2 Γ— (15 + b) = 48 Or, 15 + b = 24 Or, b = 9 cm
