    A square garden measuring 8 m on a side is surrounded by a 1 m wide path. What is the area of the path?

    A)  \[\text{8}{{\text{m}}^{\text{3}}}\]           

    B)  \[\text{9}{{\text{m}}^{\text{2}}}\]

    C)  \[\text{28 }{{\text{m}}^{\text{2}}}\]        

    D)         \[\text{36}{{\text{m}}^{\text{2}}}\]                     

    Correct Answer: D

    Solution :

    Side of garden = 8 m \[\therefore \] Its area \[={{(side)}^{2}}={{(8)}^{2}}=\text{ }64\text{ }{{m}^{2}}\] Now, side of square garden including path \[=8+1+1=\text{ }10m\] \[\therefore \] Its area \[={{(10)}^{2}}=100{{m}^{2}}\] So, area of path \[=100-64=36\text{ }{{m}^{2}}\]
