Let
L-----> the length of the new rectangle

step 2
Find the area of the new rectangle
we know that
The area of the rectangle is

we have


substitute

Answer:
The third one
Step-by-step explanation:

removing x
we have no solution
For this case, we have by definition, that an irrational number is a number that can not be expressed as a fraction
, where a and b are integers and b is nonzero.
Some examples are:
