What's the Formula for the Perimeter of a Rectangle?

'l' is the variable that stands for the length of the rectangle
'w' is the variable that stands for the width of the rectangle
The perimeter of the rectangle is the sum of the 4 sides
We can simplify the perimeter equation by combining like terms
We can factor out the 2 from each term by applying the distributive property in reverse

1. 'l' is the variable that we pick to stand for the length of the rectangle
1. 'w' is the variable that we pick to stand for the width of the rectangle
1. 'P' is the variable that stands for the perimeter
1. 'w' is the variable that we pick to stand for the width of the rectangle
2. 'l' is the variable that we pick to stand for the length of the rectangle
1. Add the 'w' variables together and the 'l' variables together!
1. 'w' is the variable that we pick to stand for the width of the rectangle
1. 'l' is the variable that we pick to stand for the length of the rectangle
1. 'w' is the variable that we pick to stand for the width of the rectangle
2. Adding 'w' to itself is the same as doubling 'w'!
1. 'l' is the variable that we pick to stand for the length of the rectangle
2. adding 'l' to itself is the same as doubling 'l'!
1. Factoring out the 2 is like applying the distributive property in reverse
1. To find the perimeter of a rectangle, just add the length and the width together and then double it!
