Area of the triangle formed by the graph of the line \[2x-3y+6=0\]along with the coordinate axes is
A)1/2 sq unit
B)2/3 sq unit
C)3 sq units
D)6 sq units
Correct Answer:
C
Solution :
[c] Required area of triangle \[=\frac{1}{2}\times OA\times OB\] \[=\frac{1}{2}\times (-\,3)\times (2)=-3\] But area cannot be negative. So, neglect the '-' sign. \[\therefore \]Required area = 3 sq units
