    Two roads of breadth 2 m each intersecting each other at right angle cross through the middle of a rectangular park whose measures are \[72m\times 48m.\] Each road is parallel to one side of the rectangle. Area of the remaining part of the park is -

    A) \[236{{m}^{2}}\]                    

    B) \[240{{m}^{2}}\]

    C) \[3216{{m}^{2}}\]                  

    D) \[3220{{m}^{2}}\]

    Correct Answer: D

    Solution :

    Area of remaining park =  Area of the park - (Area of two roads) + Area of central crossing \[72\times ~48-(72\times ~2+48\times ~2)+2\times ~2\] \[=~~3456-\left( 144+96 \right)+4\] \[=~~3460-240=\mathbf{3220}{{\mathbf{m}}^{\mathbf{2}}}\]
