George is putting trim around his rectangular deck, including the gate. He will need 44 feet of trim to do the entire deck. If the deck is 12 feet long, how wide is the deck?

20 feet
8 feet
22 feet
10 feet

Respuesta :

Answer:

10 feet

Step-by-step explanation:

perimeter of the deck=44 feet

P=2 length+ 2 width

44=2(12)+2w

44=24+2w

2w=44-24

w=20/2 ⇒ w=10 feet

check: P=2l+2w ⇒ 2(12)+2(10) ⇒ 24+20=44 feet
