    Square ABCD has side length 20 cm. point E is on \[\overline{BC},\]and the area of \[\Delta ABE\] is\[80\,\,c{{m}^{2}}\]. What is BE?            

    A)  10 cm                        

    B)  12 cm

    C)  8 cm                          

    D)  15 cm

    Correct Answer: C

    Solution :

    Area of \[\Delta ABE=80\,\,c{{m}^{2}}\] \[\frac{1}{2}\times BE\times 20\,\,cm=80\,\,c{{m}^{2}}\] \[BE=\frac{80\times 2}{20}=80\,\,cm\]
