A) 8 sq. unit
B) 12 sq. unit
C) 14 sq. unit
D) None of these
Correct Answer: C
Solution :
On solving the simultaneous equations, we get the vertices of triangle as (- 2, - 2), (2, - 2) and (0, 5). Hence, area\[=\frac{1}{2}\,\left| \,\begin{matrix} -2 & -2 & 1 \\ 2 & -2 & 1 \\ 0 & 5 & 1 \\ \end{matrix}\, \right|=14\,sq.\,units.\]
