00:00:00,640 --> 00:00:07,720
Let's do this question, are I see is a robust find, X, Y, Z, and find the perimeter of the rhombus.

2
00:00:07,900 --> 00:00:08,410
All right.

3
00:00:08,600 --> 00:00:09,490
Was the video.

4
00:00:09,640 --> 00:00:11,920
Give it a try and then let's do it together.

5
00:00:12,400 --> 00:00:12,820
All right.

6
00:00:12,820 --> 00:00:13,250
We're back.

7
00:00:13,270 --> 00:00:14,550
I hope you've given it a try.

8
00:00:14,890 --> 00:00:20,590
Now, over here, you can see that angle EOC will be equal to 90 degree, right?

9
00:00:20,740 --> 00:00:25,600
Because in a rhombus, the diagonals bisect each other at ninety degrees.

10
00:00:25,720 --> 00:00:26,190
All right.

11
00:00:26,410 --> 00:00:31,180
Now you can see that X Square is equal to five squared plus 12 square.

12
00:00:31,190 --> 00:00:36,970
Right, because triangle E, C or is the right angle triangle and X is the hypotenuse.

13
00:00:37,090 --> 00:00:42,760
So as Pythagoras theorem is square is equal to five squared plus twelve squared, that's twenty five

14
00:00:42,760 --> 00:00:45,520
plus one forty four which is equal to one sixty nine.

15
00:00:45,790 --> 00:00:49,670
Therefore X equals root of one sixty nine, that's thirteen.

16
00:00:49,840 --> 00:00:52,750
So we have found the side of the rhombus.

17
00:00:52,930 --> 00:00:58,380
Now Z over here also will be equal to thirteen because all the sides of rhombus are equal.

18
00:00:58,660 --> 00:01:00,820
And what would be the perimeter of the rhombus.

19
00:01:00,970 --> 00:01:05,300
That would be four times Z which is four in the thirteen or fifty two.

20
00:01:05,650 --> 00:01:06,100
All right.

21
00:01:06,310 --> 00:01:10,510
Now, so we have found now we need to find X and Y, OK?

22
00:01:10,660 --> 00:01:14,510
So we know that the diagonals of a rhombus bisect each other.

23
00:01:14,560 --> 00:01:15,380
Why is that so?

24
00:01:15,580 --> 00:01:17,530
Because a rhombus is a parallelogram.

25
00:01:17,530 --> 00:01:17,800
Right?

26
00:01:17,920 --> 00:01:20,810
And in a program, the diagonals bisect each other.

27
00:01:21,100 --> 00:01:21,530
All right.

28
00:01:21,640 --> 00:01:26,830
So I can say that five is equal to plus two and twelve is equal to Y plus X..

29
00:01:27,100 --> 00:01:28,180
Let's write that down.

30
00:01:28,180 --> 00:01:34,210
Five is equal to X plus two and twelve is equal to Y plus X from this five is equal to X plus two.

31
00:01:34,210 --> 00:01:40,590
We can find that X is equal to three and substitute that over here and you get Y is equal to nine to

32
00:01:40,600 --> 00:01:45,940
begin, X is equal to three, Y is equal to nine and Z is equal to thirteen.

33
00:01:45,940 --> 00:01:47,380
And that is your answer.
