Answer the question below. the smiths want to buy a 9 ft. by 12 ft. carpet and center it in a 15 ft. by 20 ft. room. what is the perimeter of the carpet? a0 feet

The perimeter of the carpet is determined by its dimensions so the dimensions of the room are irrelevant to the question.

P=2(x+y) where x and y are the dimensions, here x and y equal 9 and 12 ft so

P=2(9+12)

P=2(21)

P=42 ft
