To solve this problem, let us draw the diagram first.
00:05
So the diagram looks like this which i am drawing here.
00:08
Just look at it carefully.
00:09
After that i will simplify the problem further.
00:14
So this is the diagram which i am drawing here.
00:24
Just look at it carefully.
00:38
Now i will just write all the values with numbering.
00:44
So look at it carefully.
00:47
So here it is 1 and this distance is of 170 mm.
00:56
This distance is of 30 mm.
01:00
And here it is 2.
01:04
Here it is 3.
01:07
And this distance is of 30 mm.
01:12
And this distance from here to here is of 70 mm.
01:19
Now going forward and simplifying the problem further.
01:25
So here this distance is of 140 mm.
01:35
Here it is x'.
01:38
Here it is x.
01:41
And here it is y.
01:45
Now going forward and let us write the value of area 1.
01:49
For section 1, a1 is equal to 170 multiplication 30.
01:58
That is equal to 5100 mm square.
02:03
A2 is equal to 30 multiplication 200, which is equal to 6000 mm square...
