feet
Part A:
Choose: 144 (the number of inches)
To convert to feet: divide by 12
Choose: 108 (the number of inches)
To convert to feet: divide by 12
Therefore, the dimensions of the area rug in feet are 12 feet by 9 feet.
Part B:
To find the perimeter of the area rug in feet, we need to add up all the sides of the rectangle.
Perimeter = 2(12) + 2(9)
Perimeter = 24 + 18
Perimeter = 42 feet
Part A:
To convert the dimensions of the area rug from inches to feet, you need to divide the number of inches by 12 (since there are 12 inches in a foot) for both length and width.
For the length:
144 inches ÷ 12 = 12 feet
For the width:
108 inches ÷ 12 = 9 feet
So, the dimensions of the area rug in feet are 12 feet by 9 feet.
Part B:
To find the perimeter of the area rug in feet, you need to add up all the sides. Since it is a rectangle, the opposite sides are equal in length.
The perimeter formula for a rectangle is:
Perimeter = 2(length + width)
Substituting the values:
Perimeter = 2(12 feet + 9 feet)
Perimeter = 2(21 feet)
Perimeter = 42 feet
Therefore, the perimeter of the area rug in feet is 42 feet.
Part A:
To convert the dimensions of the area rug from inches to feet, you need to use the following conversion factor:
1 foot = 12 inches
For the length of the area rug, which is 144 inches, divide it by 12 to convert it to feet:
144 inches ÷ 12 = 12 feet
For the width of the area rug, which is 108 inches, divide it by 12 to convert it to feet:
108 inches ÷ 12 = 9 feet
So, the converted dimensions of the area rug are 12 feet by 9 feet.
Part B:
To find the perimeter of the area rug in feet, you need to add up all the sides. Since it is a rectangle, the two lengths and two widths will form the sides of the perimeter.
Perimeter = 2(length + width)
Plugging in the values, we get:
Perimeter = 2(12 feet + 9 feet)
Perimeter = 2(21 feet)
Perimeter = 42 feet
Therefore, the perimeter of the area rug is 42 feet.
