Question

Can someone please help me

Answer 1

The perimeter of the rectangle is given by the formulae,


`Perimeter= 2(l+w)`

Where

`l = s + (1)/(2)`
is the length and

`w = s`
is the width of the rectangle.


Now let us substitute into the formula,



`Perimeter= 2(s+ (1)/(2) + s)`



`Perimeter= 2(2s+ (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



`<B> A and F </B>`
