    If the length of the diagonal AC of a square ABCD is 5.2 cm, then the area of the square is :

    A) 15.12 sq.cm                   

    B) 13.52 sq.cm

    C) 12.62 sq.cm                    

    D) 10.00 sq.cm

    Correct Answer: B

    Solution :

    Sides of square = \[\frac{\left( Diagonal \right)2}{\sqrt{2}}\] \[\therefore \]Area \[=\frac{{{(Diagonal)}^{2}}}{2}=\frac{{{(5.2)}^{2}}}{2}\] \[=\frac{27.04}{2}=1352\,\,c{{m}^{2}}\]
