Answer:

8 feet

Step-by-step explanation:

In a rectangle

length (L) = 12 feet

perimeter (p) = 40 feet

width (b) = ?

We know

p = 2(L + b)

40 = 2 ( 12 + b)

40/2 = 12 + b

20 = 12 + b

b = 20 - 12

b = 8 feet

Answer:

12 feet

Step-by-step explanation:

Perimeter of rectangle = 2( l + b )

40 = 2( 12 + b )

40 = 24 + 2b

40 - 24 / 2 = b

12 feet = b (width)
