Answer:

12 inches

Step-by-step explanation:

let length be L

formula for perimeter of rectangle = 2( length + width )

2( L + 9) = 42

2L + 18 = 42

2L = 24

L = 12 inches

Answer:

C

Step-by-step explanation:

2 x length + 2 x width = perimeter

2 x length + 2 x 9 = 42

2 x length + 18 = 42

Subtract 18 from both sides

2 x length = 24

1 length = 12
