Hi, today we are solving the question in which let x and y are the base and height of the rectangle.
00:19
So from here, since the area is equal to 100 meter square given as so from here, x, y is equal to 100 meter square given as so from here x y is equal to 100 that will equal to y is equal to 100 divided by x.
00:42
The parameter p can be expressed as p is equals to 2 into x plus y.
00:51
So that will be 2 into x plus 100 divided by x.
00:56
So we want to minimize px minimize px on 0.
01:07
Or infinity.
01:09
So by taking the derivative p -x is equal to 2 into 1 minus 100 divided by x square.
01:18
So it will be equal to 0.
01:21
So from here, x is equal to plus minus 10.
01:26
So x is equals to plus minus 10.
01:27
So x is equals to 10 is the only critical value on 0, infinity.
01:34
So from here, we can take y is equals to 100 divided by 10...
