The perimeter of the rectangle is given by the formulae,

Where

is the length and

is the width of the rectangle.
Now let us substitute into the formula,


The above expression corresponds to option
F.
Now when we expand the bracket, we obtain,

This also corresponds to option A.
The correct answers are
This is an irrational number because it cannot be written as a fraction
