Answer:

Option (D)

Explanation:

Formula for the area of a triangle is,

Area of a triangle =
(1)/(2)(\text{Base})(\text{Height})

For the given triangle ABC,

Area of ΔABC =
(1)/(2)(\text{AB})(\text{CD})

Length of AB =
(y_2-y_1)

Length of CD =
(x_3-x_1)

Now area of the triangle ABC =
(1)/(2)(y_2-y_1)(x_3-x_1)

Therefore, Option (D) will be the answer.
