Question

Please explain how to solve, thank you!

**Question:**

The base of a three-dimensional figure is bound by the line \( y = x + 4 \) on the interval \( [-3, 1] \). Vertical cross sections that are perpendicular to the x-axis are right triangles with a height equal to 4.

Algebraically, what is the area of each right triangle?

**Graph Explanation:**

The graph provided shows the line \( y = x + 4 \), which intersects the y-axis at 4 and has a slope of 1. The interval is from \( x = -3 \) to \( x = 1 \). Various cross sections (represented as shaded regions) are drawn perpendicular to the x-axis, forming right triangles with one leg along the line \( y = x + 4 \) and a constant height of 4 along the y-axis.

**Answer Choices:**

- \( \circ \quad A = 2(x + 4) \)
- \( \circ \quad A = (x + 8) \)
- \( \circ \quad A = 2(x + 8) \)
- \( \circ \quad A = (x + 4) \)
