The perimeter of the rectangle is given by the formulae,

Perimeter= 2(l+w)

Where
l = s +  \frac{1}{2}
is the length and
w = s
is the width of the rectangle.


Now let us substitute into the formula,


Perimeter= 2(s+ \frac{1}{2}  + s)


Perimeter= 2(2s+ \frac{1}{2} )
The above expression corresponds to option
F.

Now when we expand the bracket, we obtain,
Perimeter= 4s+ 1
This also corresponds to option A.

The correct answers are


A and F
