When you start doing perimeter of a rectangle, you are given a length and width on a diagram. 
3 ways you can find the perimeter:
1. add all the sides
2. doubling strategy, that's a bit quicker
And then there's my favourite method... 
3. The fastest way of doing it, least calculations involved. 
See them all, decide which you like best. Ace your math.
