Question
### Problem Statement

Consider the plate shown in the figure below. The plate has a thickness of 1 m and a density of 1000 kg/m³.

a. Calculate the total mass of the plate.
b. Calculate the x and y coordinates of the plate's center of gravity.
c. Calculate the plate's moment of inertia about the z-axis passing through the origin.
d. Calculate the plate’s moment of inertia through an axis parallel to the z-axis passing through the plate's center of gravity.

### Figure Description

The diagram depicts an L-shaped plate with the following dimensions:
- The horizontal base of the plate measures 8 m in total length, segmented into 4 m and another 4 m sections.
- The vertical side of the plate is composed of a 3 m segment on the right side.
- The plate has a consistent thickness of 1 m.

The plate's shape resembles a horizontal rectangle intersected by a vertical rectangle at the right.

### Explanation of Graphs/Diagrams

The figure illustrates the plate with a marked origin at the lower left corner, alongside labeled axes for reference in calculating various properties.

The question involves using concepts like mass calculation, center of gravity, and moments of inertia, essential in physics and engineering to understand material behavior and dynamics.
