W=2L-5
-------------
A=L*W
=L(2L-5)
=2L²-5L
-------------
dA/dL=4L-5
When dA/dL=0,
4L-5=0
4L=5
L=5/4
----------------
When L=5/4
A=5/4*(2*(5/4)-5)
=5/4*(10/4-20/4)
=5/4*((-10)/4)
=5/4*(-5/2)
=-25/8

2.36................!!!!!!!!!!!
An irrational number that lies between the two given ones, 0.6333.... and 0.64 is:
√7 - 2.01 =0.63575...
<h3>How to find an irrational number between the two given ones?</h3>
Remember that an irrational number is a number that can't be written as the quotient between two integers.
Here we want to find two numbers between 0.6333 (where the 3 repeats infinitely) and 0.64
So we cold try to find a number like:
6.3349412490184...
Such that there is no pattern (because if there were a pattern, it would not be an irrational number).
An example of this can be, for example:
√7 = 2.64575...
This is an irrational number.
Now, if we subtract 2.01 from that we will get:
√7 - 2.01 = 2.64575... - 2.01 = 0.63575...
This is an irrational number and lies between the two given ones, then we conclude that √7 - 2.01 =0.63575... is a correct option.
