Math Problem Statement

Plot and connect the points in the order listed below. When you are done, find the area of the resulting figure. A(-4, 8), B(6, 8), C(-1, 0), D(6, 0), E(6, -4), F(-4, -4)

Solution

The image shows a geometric problem where the user needs to calculate the area of a polygon created by connecting the given points. The coordinates provided are:

  • A(4,8)A(-4, 8)
  • B(6,8)B(6, 8)
  • C(1,0)C(-1, 0)
  • D(6,0)D(6, 0)
  • E(6,4)E(6, -4)
  • F(4,4)F(-4, -4)

To find the area of the polygon, we can use the Shoelace Theorem (or Gauss's area formula) for calculating the area of a polygon when the coordinates of the vertices are given.

Steps:

  1. List the coordinates of the vertices in order: Vertices: A(4,8),B(6,8),C(1,0),D(6,0),E(6,4),F(4,4)\text{Vertices: } A(-4, 8), B(6, 8), C(-1, 0), D(6, 0), E(6, -4), F(-4, -4)
  2. Apply the Shoelace Theorem: Area=12i=1n1(xiyi+1yixi+1)\text{Area} = \frac{1}{2} \left| \sum_{i=1}^{n-1} (x_i y_{i+1} - y_i x_{i+1}) \right| Where (x1,y1),(x2,y2),(x_1, y_1), (x_2, y_2), \dots are the coordinates of the vertices.

Let's calculate the area step by step.
