I have a really silly question, why is the perimeter of this figure p=(6+8)*2?

a=b, c=d. because a,b,c, and d form a rectangle. Now, since |dw:1333412617503:dw|
X+c=6, and y+b=8, we can substitute c=d and a=b to get x+d=6, and y+a=8.
now the perimeter of the figure is 2(x+d)+2(y+a), or, in other words, 2(x+d+y+a). This is equal to a rectangle with side length 6 and 8.
What I needed to know was 2(x+d+y+a) because I didn't remember how to calculate the perimeter...Thank you!
Yes, I found it sort of silly to explain too (I couldn't actually put it into good words or a good drawing :S)
