In this problem, we're going to find the perimeter of the given shape.
00:06
Now, remember that perimeter is the sum of all sides of a shape, which means we're going to add all the sides together.
00:16
I also notice that when i look at the sides of this shape, i notice that some have variables and some do not.
00:24
I cannot combine or add any sides that have different variables.
00:31
Everything has to have light turks.
00:34
So i'm going to only be able to combine my like turks.
00:39
So let's find one like term that we can go ahead and we can combine.
00:43
Let's start with 4r.
00:47
The variable of 4r is r.
00:50
There's only one other term that has an r and it's 3r.
00:57
So i can combine 3r...
