    A) 56 cm                 

    B)        64 cm

    C) 67 cm                 

    D)        60 cm

    E) None of these

    Correct Answer: D

    Solution :

    Option (d) is correct. Side of square A = 7 cm. Perimeter of square = 28 cm Length of rectangle B = 12 cm. Breadth of rectangle B = 4 cm Perimeter of rectangle \[B=2\times \left( 12+4 \right)cm=\] \[\left( 2\times 16 \right)cm=32\text{ }cm\] So, the required sum of perimeters \[=\left( 28+32 \right)\] \[cm=60\text{ }cm\] Rest of the options is incorrect because of the correctness of option (d).
