Answer 1

The answer is b.
40

Explanation:

So the width is `6+2/3` and the length is 2 times the width.

We know that in order to find the perimeter of the rectangle we apply this simple equation that goes like `P=2W+2L`
wherein `P` is the perimeter, `W` is the width and `L` is the length.

So we come to simplified equation that goes like
`P=2(6+3/2) + 2*2(6 + 3/2)`
which gives
`P=(6 + 3/2)(4+2)`

`P=(6+3/2)*6`

`P=36+4`

`P = 40`

I hope that wasn't too complicated.
