A) \[13\] square units
B) \[13.5\] square units
C) \[14\] square units
D) \[14.5\] square units
Correct Answer: B
Solution :
\[\frac{1}{x}+\frac{y}{(-1)}=1\] ?..(i) \[\Rightarrow \,\,\,\,\,\frac{x}{4}+\frac{y}{8}=1\] ?.. (ii) From eq. (i) & (ii)- \[x-y=1\] \[\frac{2x+y=8}{3x=9}\Rightarrow x=3\Rightarrow CD=3\] Area of \[\Delta ABC=\frac{1}{2}\times 9\times 3\] \[~=\frac{27}{2}~=\underline{\mathbf{13}\mathbf{.5~square units}}\]You need to login to perform this action.
