00:00Hi kids today, we will learn what is parameter
00:07Suppose you are making a beautiful birthday greeting and you want to make its border
00:14Then how much lace you require to make its border?
00:19Let me help you calculate
00:23You require lace equal to the length of the border of the card
00:30See the figure in
00:33order to calculate boundary
00:35You need to add the lengths of all sides of a closed figure
00:42so
00:43Adding all sides we get 20 centimeters
00:49Here 20 centimeters is the parameter of your card
00:55Let's take another example
00:58Can you find the parameter of this square of side 5 centimeters
01:06Look at the figure
01:10We will add the lengths of all sides of this square
01:15So we get parameter of this square is 20 centimeters
01:22Good
01:25Let's take one more example, can you find the parameter of this triangle?
01:34Let's add the lengths of all sides
01:38Yes
01:39You get 11 centimeters
01:43so parameter of this triangle is
01:4611 centimeters
01:48Good
01:51So what have we learned?
01:54we have learned parameter is the length of boundary of a closed figure and
02:02We calculate it by adding the lengths of all sides of a closed figure
02:08Then and take a quiz to learn more
02:12Bye. Bye
