Plzzz help

Answer 1

`121=6w`

Explanation:

Formula for perimeter of a rectangle:

`P=2l+2w`

`w` = width

`l` = length

Since the length is twice the width,

`l=2w`.

So, plugging these values into the formula, as well as the given perimeter of 121 feet, we get,

`121 = 2(2w)+2w`

And after some simplification, we are left with,

`121 = 6w`
