00:00:00,730 --> 00:00:07,630
Let's do this question if the diagonal B of a quadrilateral is doubled and the heights each one and

2
00:00:07,630 --> 00:00:14,820
it's two falling on the other half, then the area of the quadrilateral is all right, was the video.

3
00:00:15,010 --> 00:00:16,990
Give it a try and then let's do it together.

4
00:00:17,500 --> 00:00:17,920
All right.

5
00:00:17,920 --> 00:00:19,610
Let's do it together over here.

6
00:00:19,630 --> 00:00:24,270
We know that area of equal is equal to half B into each one.

7
00:00:24,280 --> 00:00:25,980
Plus it's two right now.

8
00:00:25,990 --> 00:00:28,330
Let's find out the modified area.

9
00:00:28,540 --> 00:00:34,150
It's mentioned that the diagonal is doubled and each of the heights are half right.

10
00:00:34,420 --> 00:00:40,870
But we get to the over here because we had the deal here and each one becomes it's run by two and it's

11
00:00:40,870 --> 00:00:42,580
two becomes it's two by two.

12
00:00:42,950 --> 00:00:43,410
All right.

13
00:00:43,540 --> 00:00:48,070
Now, over here, you can see that this is equal to half the each one.

14
00:00:48,070 --> 00:00:48,910
Plus it's two.

15
00:00:48,910 --> 00:00:51,970
Right, because you can cancel out these two and these two.

16
00:00:52,480 --> 00:00:52,900
All right.

17
00:00:53,270 --> 00:00:55,000
You see that these two are equal.

18
00:00:55,240 --> 00:00:59,320
That is is equal to eight and therefore the areas are the same.
