So i'm supposed to find the perimeter of this figure, and it is a six -sided polygon.
00:10
I put all the sides in different colors because it just was very awkward to write or draw from the book.
00:19
But to find the perimeter, we simply need to add all the side lengths.
00:37
So we're going to be adding six sides together.
00:42
So we have that perimeter equals.
00:45
We'll go countercockboy starting with 7.
00:52
7 plus 2x plus 4 z plus 8 plus 3x plus 5x.
01:11
I do have some like terms here.
01:16
So i'm going to circle all the constants.
01:24
And i'm just going to do that sidework here of adding 7 and 8 that equals 15...
