Okay, so for me, the easiest way to do these is to always draw a picture.
00:06
So i'm going to draw a rectangle.
00:10
Right, that's not a perfect rectangle, but it's okay.
00:12
I do my best.
00:13
All right, so it says that the length is twice the width.
00:16
So i'm going to say, here's the width.
00:18
And the length is going to be twice the width.
00:20
Boom.
00:21
Right.
00:22
So this equals the length, right? it's the length, but it says that it's twice the width.
00:26
So i'm just going to say 2w.
00:28
Now the perimeter is going to be, a perimeter is going to be twice.
00:34
Twice twice the length or plus i'm sorry i don't know what i'm thinking plus twice the width all right so we know that the length is going to be 2w so i'm going to rewrite that as equal to 2 times 2 w plus 2 w now i also know that the perimeter is 200 so now i have an equation that i can solve i'm just going to combine like terms two times two is four and then plus 2 is 6...
