Hello, lisamae!

Did you make a sketch?

i have a rectangular garden.

i need 42m of fencing to go all the way around.

the length of the garden is twice as long as the width.

what is the length and the width? Code:

2x
*--------------*
| |
x | | x
| |
*--------------*
2x

Let the width of the garden be *x*.

Then the length is *2x*.

The amount of fencing is: .x + 2x + x + 2x .= .6x

We are told that the amount of fencing is 42 feet.

There is our equation . . . .6x .= .42

Hence: .x = 7 .and .2x = 14

Therefore, the garden will be 7-by-14 feet.
