How you measure curved line with thread?
Use a thread to measure the length of curved line AB. Put a knot on the thread near one of its end. Place this knot on on point A. Now, place a small portion of thread along the line, keeping it taut using your fingers and thumbs. Hold the thread at this end point with one hand. Using other hand, stretch a little more portion of the thread along the curved line. Go on repeating this process till the other end B of the curved line is reached
How do you measure the surface area using the length and width?
Multiply them.
Can you measure a person length using meters?
No. You can only measure a person's length using some sort of marked off stick or measuring tape. After you know the person's length, you can describe it in meters if you want to tell others about it.
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.
Can you measure a paperclip with kilometers?
You could measure the length or width of it but you would have a decimal. You should be using centimeters.
