    DIRECTIONS: Passage ? 2 Read the passage(s) given below and answer the questions that follow A rectangular park is of dimensions 90 m by 80 m. Four paths pass through the park such that two paths each of width 2m are parallel to the breadth and two paths each of width 3 m are parallel to the length. Total area of the two roads along the breadth is

    A)  \[320\,{{m}^{2}}\]         

    B)  \[160\,{{m}^{2}}\]

    C)  \[230\,{{m}^{2}}\]             

    D)  \[270\,{{m}^{2}}\]

    Correct Answer: A

    Solution :

        Length of the road = 80 m Breadth of the road = 2 m \[\therefore \]  Area of the road \[=(80\times 2)=160\,{{m}^{2}}\] \[\therefore \] Total area of the two roads along the breadth\[=2\times 160=320\,{{m}^{2}}.\]
