    AB is a line segment 2011 cm long. Squares are drawn as in the diagram. The length of the broken line segment A, \[{{A}_{1}}\]\[{{A}_{2}}\]\[{{A}_{3}}\]\[{{A}_{4}}\]\[{{A}_{5}}\]\[{{A}_{6}}\]\[{{A}_{7}}\]\[{{A}_{8}}\]\[{{A}_{9}}\]\[{{A}_{10}}\]\[{{A}_{11}}\]\[{{A}_{12}}\]\[B\]is

    A)  2011 cm        

    B)  4022 cm      

    C)  6033 cm                    

    D)  8044 cm

    Correct Answer: C

    Solution :

    The length of broken line \[A{{A}_{1}}\] ............. \[{{A}_{12}}\]B is same as \[3\left[ AP+PQ+QR+RS+ST+TB \right]\] \[=3AB=3\times 2011\,cm=6033\,cm\]
