. Susan's room is 9 feet long. The area of the room is 54 square feet.What is the perimeter of her room?
A = Area
W = Width
L = Length
P = Perimeter
A = W * L
54 = W * 9 Divide both sides by 9
54 / 9 = W
6 = W
W = 6 ft
P = 2 ( W + L )
P = 2 ( 9 + 6 )
P = 2 * 15
P = 30 ft
A = L * W
54 = 9 * W
54/9 = W
6 = W
P = 2L + 2W
P = (2 * 9) + (2 * 6)
P = 18 + 12
P = 30 feet
To find the perimeter of Susan's room, we need to know the width of the room. The area of the room is given as 54 square feet, but the length is given as 9 feet. Without the width, it is not possible to determine the exact dimensions or calculate the perimeter of the room.
To find the perimeter of Susan's room, we need to know the width of the room. The question only provides the length, which is 9 feet, and the area, which is 54 square feet.
However, without the width, we cannot directly calculate the perimeter. The perimeter of a rectangle is given by the formula:
Perimeter = 2 (length + width)
Since we only have the length, we need to find the width of the room first.
To calculate the width, we can use the formula for the area of a rectangle:
Area = length * width
We know that the area of the room is 54 square feet, and the length is 9 feet. Plugging these values into the formula, we get:
54 = 9 * width
Dividing both sides of the equation by 9, we find:
width = 54 / 9
Simplifying, we get:
width = 6 feet
Now that we have both the length and width of the room, we can calculate the perimeter using the formula:
Perimeter = 2 (length + width)
Plugging in the values:
Perimeter = 2 (9 + 6)
Simplifying, we find:
Perimeter = 2 * 15
Perimeter = 30 feet
Therefore, the perimeter of Susan's room is 30 feet.
