3 sq. units

B

2 sq. units

C

0

D

1 sq. unit

Correct Answer :

0

Solution :

The correct option is 0.

To find the area of a triangle with given vertices, we can use the coordinate geometry formula for the area of a triangle. Let the vertices of the triangle be:
( x1 , y1 ) = ( 2 , 3 )
( x2 , y2 ) = ( 4 , 1 )
( x3 , y3 ) = ( 5 , 0 )

The standard formula for the area of a triangle with vertices (x1,y1), (x2,y2), and (x3,y3) is given by:
Area = 12 | x1 ( y2 y3 ) + x2 ( y3 y1 ) + x3 ( y1 y2 ) |

Let us substitute the coordinate values of our vertices into this formula:
Area = 12 | 2 ( 1 0 ) + 4 ( 0 3 ) + 5 ( 3 1 ) |

Now, we simplify the terms inside the absolute value brackets step-by-step:
First term: 2(10)=2(1)=2
Second term: 4(03)=4(3)=12
Third term: 5(31)=5(2)=10

Substitute these values back into the expression:
Area = 12 | 2 12 + 10 |

Add the terms inside the absolute value:
2 12 + 10 = 10 + 10 = 0

Thus, the area becomes:
Area = 12 | 0 | = 0

Since the area of the triangle is 0, it means that the three points (2,3), (4,1), and (5,0) are collinear (they lie on a single straight line) and do not form a proper triangle. Therefore, the area is 0 square units.
