    The breadth of a rectangle is 9 cm shorter than its length. If the length is 20 cm, then the perimeter of rectangle is:

    A) 44 cm

    B)                                56 cm

    C) 58 cm                 

    D)        62 cm

    E) None of these

    Correct Answer: D

    Solution :

    Explanation: Option (d) is correct. Here, length of rectangle = 20 cm Therefore, its breadth = (\[20-9\]) cm = 11 cm Hence, the required perimeter = \[2\times \](length + breadth) \[=2\times (20+11)\text{ cm}=(2\times 31)\text{ cm}=62\text{ cm}\]
