Answer:
L+W×2 or L+L+W+W
Step-by-step explanation:
All you do to find the perimeter of any shape is adding up all of the sides.
for example:
let's say I have a rectangle and the long side of the shape (the Length) is 8 inches, and the shorter side of the rectangle (the Width) is 4 inches. I would add 8+8 and 4+4, then I would have 16+8, which equals 24in, so the answer would be 24 inches.
I hope this helps! good luck!
