For perimeter to you add or what? i'm still confused on that

To find the perimeter, you must add all sides of the shape. Hope this Helps!

P (Perimeter) = L (Length)+ L (Length) + W (Width) + W (Width)

OR you can do-

P (Perimeter) = L (Length) times 2 + W (Width) times 2

(They will still equal the same answer)

I’m going to infer you said parallel.solve for yy= -1/2x+7/4lines that are parallel have the same slope, different y intercept.so we know m is -1/2then from there solve for y intercept.
