Oh, dude, the perimeter of a rectangle is just adding up all the sides, so for a 12ft by 8ft rectangle, you just do 12 + 12 + 8 + 8, which equals 40 feet. It's like measuring the sides of a fence but with math instead of a tape measure.

There's no fun in playing it safe. Why not try something a little unhinged?
