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.
