Answer:
Area: 15 square units, Perimeter: 16 units.
Step-by-step explanation:
First, we need to plot our points on a graph, we put the points at (3, 4), (3, 9), (6, 9), and (6, 4). Check the attached image for the graph. Now, for the area, we count two of the different sides and multiply the numbers. In our case, we have 2 sides that are 3 units, and 2 sides that are 5 units. Let's multiply 3 and 5. For the area, we have 15 (3x5). Now for the perimeter, we need to add all the sides together, 3+3+5+5. When we do this, we get 16. So that's it, the perimeter is 16 units, and the area is 15 square units. Make sure to put square units for only area, not perimeter. I hope this helps!
