Answer 1

Answer:

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

Step-by-step 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

$42=2(12+y)$

$21=(12+y)$

$y=21-12=9\ ft$
