    Find the area of each bedroom and kitchen in the layout.

    A) \[35{{m}^{2}},\,15\,{{m}^{2}}\]

    B) \[~27{{m}^{2}},\text{ }30{{m}^{2}}\]

    C) \[40{{m}^{2}},30{{m}^{2}}\]

    D) \[30{{m}^{2}},\text{ }35{{m}^{2}}\]

    Correct Answer: D

    Solution :

    On solving Eqs. (i) and (ii), we get x = 6 and y = 7
    \[\therefore\] Area of each bedroom
    \[=5\times x=5\times 6=30\,{{m}^{2}}\]
     and area of kitchen
                \[=5\times y=5\times 7=35\,{{m}^{2}}\]
