Answer 1

The width of the rectangular garden is
`9\ ft`

Explanation:

Let

x-----> the length of the rectangular garden

y----> the width of the rectangular garden

we know that

The perimeter of the rectangular garden is equal to

`P=2(x+y)` ----> equation A

we have

`P=42\ ft`

`x=12\ ft`

substitute the values in the equation A and solve for y

`42=2(12+y)`

`21=(12+y)`

`y=21-12=9\ ft`
