 This is another example of finding perimeter in area based on a coordinate plane. So what you see here is you have four points, m, a, t, and h, and the first thing that you want to do is put those points on your coordinate plane. Why is that important? Because once you put these points on your graph, you can very clearly see what kind of polygon it is or what kind of shape it is. And so take a minute and plot your four points, m, a, t, and h, and you see the result is a rectangle. And the nice thing here is the rectangle is made up of all horizontal and vertical lines or segments I should say. And so we can easily count to figure out how long it is or how far it is from m to h. So just count 1, 2, 3, 4, 5, 6 units, which means this side is 6. And from t to h, 1, 2, 3, 4, which means a to m is also 4. We can now go ahead and find perimeter because perimeter is just adding up all the sides. And so 4 plus 6 plus 4 plus 6, we get a perimeter of 20. Now here, we're just going to call it units because we don't know if this is in inches or miles or whatever. So if you want to, just abbreviate that with a u, 20 units. Area, once again, it's really important that you drew the picture because in order to do area, we need to know what formula to use. In this case, we're using the formula for area of a rectangle. And so that's going to be base times height. In this case, 4 times 6, which is 24 square units.
