For part d, we need to find the appropriate region in which the question is asking.
Remember that a triangle is made up of three straight lines. In this situation, the three lines of interest are the straight line 5y - 3x - 8 = 0, the x-axis and the y-axis. The region enclosed by the three lines, which I have shaded in red, is the area of the triangle to be found. I have included the diagram for reference.
To find the area of the triangle, we need the base of the triangle and the height of the triangle. To do so, we need to find the x-intercept and the y-intercept. This facilitates the obtaining of the base and the height of the triangle respectively.
