    Area of shaded square formed by the joining the mid-points of the sides of a square with area\[16\,{{m}^{2}}\]is

    A)  \[16\,{{m}^{2}}\]                           

    B)  \[4\,{{m}^{2}}\]

    C)  \[10\,{{m}^{2}}\]                           

    D)  \[8\,{{m}^{2}}\]

    Correct Answer: D

    Solution :

        Area of square ABCD = 16 side\[\times \]side = 16 \[\Rightarrow \] side = 4 m. \[{{E}_{1}}\,{{F}_{1}}\,G\]and\[H\]are mid-points \[\therefore \]  Area of 4 triangles\[=4\left[ \frac{1}{2}\times 2\times 2 \right]\]                            \[=8\,{{m}^{2}}.\] Now, area of shaded Square\[=16-8=8\,{{m}^{2}}.\]
