Hello students today our question is a geometry students wants to draw a rectangle inscribes in a semicircle of radius 12.
00:08
So suppose this is our semicircle and the students wants to draw a rectangle in it.
00:19
Suppose this is the rectangle in it.
00:26
If one side must be on the semicircle's diameter, what is the area of the largest rectangle that can student draw? so firstly we will consider that this is the diameter and this is r.
00:46
This is r which is equal to 12.
00:50
Now we will consider that the length of this rectangle is x.
00:57
So this will become x divided by 2 and this will become x divided by 2 and the height is and this length is this length.
01:09
Is y.
01:10
So we know that the x by pythagorosurum x square x square plus y square.
01:22
So by pythagoras theorem we can write that x divided by two whole square plus y square is equal to 12 whole square.
01:33
So we will find the value of y from here which will be equal to 12 whole square minus x divided by two whole square square root.
01:45
Now we will find the area.
01:47
Area of rectangle is length multiplied by breath...
