Respuesta :
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
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
The perimeter of the carpet is 42 ft .
What is a Perimeter ?
Perimeter is the distance around the edge of a shape
The perimeter of a rectangle of side l and b where l is the length and b is the breadth is given by 2(l +b)
Here the given carpet is a rectangle .
l = 9 ft
b = 12 ft
perimeter of the carpet = 2 ( 9 + 12 ) = 2 * 21 = 42 ft
Therefore the perimeter of the carpet is 42 ft .
