Find the perimeter of the rectangle pictured. (Attached in a comment) Was wondering if you would use FOIL to solve this :P A. 11x + 9 B. 22x - 2 C. 18x - 20 D. 11x - 1
here
I just dont like using FOIL and my school said you cant find the perimeter any other easier shorter way :P hoping there was one
Yeah, there really isn't another way to find the perimeter in that case. It's always LengthxWidth for a rectangle.
:P that rly sucks. thanx anyways tho! (:
Err what am I thinking, that's area. For the perimeter, you wouldn't really need to foil. Just multiply each by 2 and then add them together.
YAY!! I thought i could do that too!! But then my teachers were like no no no you can only FOIL haha yea i was wondering why you sad L*W ^_^
2(4x+8)+2(9x-5) =4x+8+19x-10 =22x-2
Wow, many typos. You get the idea.
lol yea now im just not gonna tell my teacher im not doing FOIL.... same answer!! xD and yea i get the idea ^^
Haha, all right.
20x lol?
