How can the length be measured along a curved line?
Put a string over the curved line. Measure the string. If you want to do it by calculations for some known function, use integration. Divide the curved line into many small pieces, so that each piece can be approximated by a straight line, and use Pythagoras' Formula for each piece: length = square root of (width2 + height2), using the width and height of the piece. In calculus books, you'll find methods that can get you an exact result in some cases.

How does different shapes have the same perimeter?
That should not surprise you. Here's a thought that might make you more comfortable with it: -- Take a good sized piece of string. Tie the ends together. -- Now you have a big limp loop. Drop it down on the ground. -- How many different shapes can you make out of it ? A square ? A circle ? Different short fat rectangles ? Triangles ? Different long skinny rectangles ? Odd-ball shapes with 9 sides or 17 sides ? Shapes with some straight sides and some curved sides ? You can push the string loop around into millions of different shapes. The string loop is the perimeter of every one of them.
