Answer:

The correct option is;

10.5

Step-by-step explanation:

The given coordinates are;

Triangle XYZ

Coordinates of X = (5, -3)

Coordinates of Y = (8, -1)

Coordinates of Z = (5, 4)

Coordinates of point W = (5, -1)

Given that W is on segment XZ, we have;

Length of segment XZ = A base of the triangle is given by the relation;

[tex]Length \ of \ segment = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]

Where

(x₁, y₁) = (5, -3)

(x₂, y₂) = (5, 4)

Therefore, we have;

[tex]Length \ of \ XZ= \sqrt{\left (4-(-3) \right )^{2}+\left (5-5 \right )^{2}}[/tex] = 7

The length of segment YW is also given as follows;

[tex]Length \ of \ YW= \sqrt{\left (-1-(-1) \right )^{2}+\left (5-8 \right )^{2}} = 3[/tex]

Given that the height of the triangle XYZ is given by segment  YW, the area of triangle XYZ = 1/2 × Base × Height = 1/2×7×3 = 21/2 = 10.5

The area of triangle XYZ  = 10.5.

Answer:

10.5
