Welcome to the Perimeter and Area of Polygons section at. Finding the perimeter or area of a rectangle in the coordinate plane.Area involving rectangles and triangles.Finding the area of a trapezoid on a grid by using triangles and rectangles. ![]() Finding the area of a right triangle or its corresponding rectangle.Finding the area of a right triangle on a grid.Finding the side length of a rectangle given its perimeter or area.Word problem involving the area of a square or a rectangle.Areas of rectangles with the same perimeter.Distinguishing between the area and perimeter of a rectangle.Area of a rectangle involving fractions.Perimeter of a piecewise rectangular figure.Sides of polygons having the same perimeter.The distance all the way around the outside of this figure, or the perimeter of the figure, is 32 centimeters. And we're talking about centimeters here, so 32 centimeters. So another way we could add this is 20 plus 12, which is a total of 32. 16, let's see, six ones plus six more ones is 12 ones, and one 10 plus another 10, or 10 plus 10 is 20. Eight plus eight is another 16, so we have a 16 and a 16. Nine plus one is 10, and 10 plus six is 16. See, instead of seven, I could do nine plus one and six, 'cause that's the same as seven. So we can start, five plus three is eight. So if we combine them or add them, we'll know the perimeter. So now we know the entire, all of the lengths, around the outside. So if we have four centimeters plus another three centimeters, that's a total of seven more centimeters. So from here to here is another four centimeters. And where that three centimeters left off, this four centimeters, this length, picked up. Well then, that same length over here is also three centimeters. So what we can do is, we can look over here and say, this length right here If this little ant, she walked the whole way, we've gotta know theĮntire distance she walked. ![]() But to find perimeter, we need the distanceĪround the entire outside. And then, we head up this side, and uh oh, we don't have a label. This side right here, which is another four centimeters, and as we keep going, across the bottom, we have another nine centimeters. So we have five centimeters, plus, moving down the side here, we have another three centimeters, and then going across, next distance is four centimeters. We can see that this side length is five centimeters. Of the side lengths, we'll have the perimeter, or the distance around Length of this side, and once we combine all The length of this side, and combine it with the So to find that, what we can do is figure out how long is this side, and then combine it with Outside of this figure, how far she walked would be the perimeter. So in this case, if I were to walk around the outside, or maybe a human's too big, if an awesome little ant was to walk all the way around the Perimeter is the distance all the way around the outside of a shape. ![]() Perimeter of the figure below? So down here, we have this figure, and we are asked to find the perimeter of this figure.
