Answer: 12 units²
Finding what formula to use:
I can see that we have pairs of points with the same x-coordinate values and the same y-coordinate values. This leads me to believe the polygon given is a rectangle. To check, I will graph the points given. After graphing, it appears I was correct! Now we can solve this problem.
-> See attached
Explanation:
Since this is a rectangle, we will use A = L * W
A = L * W
A = 4 * 3
A = 12
A = 12 units²
The area of the given polygon is 12 units².
