A meter rule.
It is necessary because measuring tools help you measure the length of an object accurately.
To measure a foot length you could use a ruler, a yard stick, a tape measure, or any object that you knew was precisely one foot long on a side or edge.
Use a string: put your finger where the string is at the edge of the object, then use a ruler to measure the tip of the string to your finger. Or use a protractor: each degree equals 1/16 of an inch.

You would use a ruler or measuring tape to measure the length of an object. Place the edge of the ruler or tape at one end of the object and note the measurement where the object ends. Make sure to read the measurement carefully to get an accurate length.

You could use a ruler or a measuring tape to measure the length of an object. Both tools have markings that allow you to accurately determine the distance from one point to another.

A ruler or a measuring tape can be used to measure a straight sided object. Simply lay the ruler or tape along the object's edge and read the measurement where it stops.
To estimate the length of a cat's body without the use of a ruler to measure, use an object that an estimate measurement is known to estimate the length of the cat.
One way to measure an irregular shaped object is to use a water displacement method. By placing the object in a container of water and observing the change in water level, you can calculate the volume of the object. Another method is to use a string to outline the shape of the object and measure the length of the string to determine its dimensions.
