introduction long back do you know how people used to measure the lengths of objects they used their palm forearm or feet to measure the length of the objects but these methods never gave accurate results nowadays we make use of ruler metric scale and measuring tape to measure the accurate length and height of the objects let us learn the correct method of using a scale objectives at the end of this lesson you will be able to measure the length of objects using a ruler measure length in meters and centimeter understand the relation between meter and centimeter I need four centimeter long paper what will I use to measure the length yes as you are correct a ruler will help me to measure Liang you find many divisions on the margin of the ruler some lines are longer while others are smaller the longer lines represent the number in centimeters the small lines between two long lines represent divisions of centimeter now we will learn to read the scale example this is 2 centimeters this is 1/2 centimeter similarly this is 4 and 1/2 centimeter yoku want to measure the length of different objects will you help them click on each object to measure its length Azula comes in different lengths the first ruler seen and measure length up to 15 centimeters the second ruler seen can measure length up to 30 centimeters but a ruler cannot measure all objects jhula is used to measure only short length objects such as pencil stick notebook duster comb etc a measuring tape is used to measure long things your mother is in market to buy shirt cloth can the shopkeeper measure a shirt piece with a ruler yes he can measure but the work would be tedious and time-consuming he measures it with the help of metric team it will take less time and less effort one meter is equal to 100 centimeters we can measure the height of the Almira by using measuring tape the height of the Almira is 200 centimeters therefore we can say that the height of the Almira is 2 meter similarly the length of walking stick is 100 centimeter or we can say 1 meter you let us compare the length of the various things some of the objects have their length in meters while some of them are so small that they are measured in centimeters only length of a bread loaf is expressed in centimeters the length of a matchbox is expressed in centimeters the length of a skipping-rope is expressed in meters the length of a bus is expressed in meters summary let us summarize what we have left we use ruler metric scale and measuring tape to measure length ruler is used to measure length of small objects length can be measured in centimeters and meters one meter is equal to 100 centimeter
