With reference to the conventional Cartesian (x, y) coordinate system, the vertices of a triangle have the following coordinates; (x1, y1) = (1, 0); (x2, y2) = (2, 2); (x3, y3) = (4, 3). The area of the triangle is equal to A. \[\frac{3}{2}\] B. \[\frac{3}{4}\] C. \[\frac{4}{5}\] D. \[\frac{5}{2}\]

The area of a triangle can be calculated using the formula:

$$A = \frac{1}{2} \cdot b \cdot h$$

where $b$ is the base of the triangle and $h$ is the height of the triangle.

In this case, the base of the triangle is the line segment connecting $(1, 0)$ and $(2, 2)$. The length of this line segment can be calculated using the Pythagorean theorem:

$$|(x_1 – x_2)|^2 + |(y_1 – y_2)|^2 = d^2$$

where $(x_1, y_1)$ and $(x_2, y_2)$ are the coordinates of the two endpoints of the line segment, and $d$ is the length of the line segment.

In this case, we have:

$$|(1 – 2)|^2 + |(0 – 2)|^2 = d^2$$

$$1^2 + 4^2 = d^2$$

$$d = \sqrt{1 + 16} = \sqrt{17}$$

The height of the triangle is the perpendicular distance from $(1, 0)$ to the line segment connecting $(2, 2)$ and $(4, 3)$. This can be calculated using the formula:

$$h = \sqrt{(x_1 – x_2)^2 + (y_1 – y_2)^2}$$

In this case, we have:

$$h = \sqrt{(1 – 2)^2 + (0 – 2)^2} = \sqrt{5}$$

Therefore, the area of the triangle is:

$$A = \frac{1}{2} \cdot \sqrt{17} \cdot \sqrt{5} = \frac{3}{2}$$

Therefore, the correct answer is $\boxed{\frac{3}{2}}$.
