    D) \[12\,\,m\times 8\,\,m\]  

    Correct Answer: A

    Solution :

    Let the breadth of garden =xm \[\therefore \]      length = (x+4) m \[\therefore \]      \[x+(x+4)=36\] \[\Rightarrow \]   \[2x=32\] \[\Rightarrow \]   \[x=16\,\,m\] \[\therefore \]dimensions are \[(16+4)\,\,m\times 16\,\,m\] \[=20\,\,m\times 16\,\,m\]
