Quadrupled.
00:01
Okay, so here's the dimensions of a rectangle.
00:05
They have quadrupled.
00:07
If the original perimeter of the rectangle was 20 feet, okay? so if 20 feet was the original rectangle, okay? so that's the perimeter.
00:27
What is the new perimeter? so let's take a look.
00:31
Say i had a triangle that was, these are five, five, ten, and ten, okay? and the perimeter right now, okay, would be 10 plus 10 plus 10, so it was 30, say.
00:47
Say it quadrupled, okay? i'm going to multiply everything by 4.
00:53
That's to quadruple it by multiplying it by 4.
00:56
So i'd get 40, 20, 40, and 20...
