You’re building a rectangular frame 10 inches by 11 inches. How many feet of wood do you need?
P = 2L + 2W
P = 20 + 22
P = 42 inches = 3 feet, 6 inches
To find out how many feet of wood you need for the rectangular frame, we need to determine the perimeter of the frame.
The perimeter of a rectangular frame is calculated by adding up the lengths of all four sides. In this case, we have a frame with sides measuring 10 inches and 11 inches.
The formula to find the perimeter is:
Perimeter = 2 * (length + width)
Let's substitute the values into the formula:
Perimeter = 2 * (10 inches + 11 inches)
Calculating:
Perimeter = 2 * (21 inches)
Perimeter = 42 inches
Now, we need to convert the result from inches to feet since we want the answer in feet. Since 1 foot equals to 12 inches, we can divide the length in inches by 12 to convert it to feet.
Let's convert the inches to feet:
Perimeter in feet = 42 inches / 12 inches/foot
Calculating:
Perimeter in feet = 3.5 feet
Therefore, you would need 3.5 feet of wood to build the rectangular frame.
To find out how many feet of wood you need, you need to calculate the perimeter of the rectangular frame.
Perimeter of a rectangle = 2 * (Length + Width)
Given that the length is 10 inches and the width is 11 inches:
Perimeter = 2 * (10 + 11) = 2 * 21 = 42 inches
Since there are 12 inches in a foot, to convert inches to feet, divide the number of inches by 12:
42 inches ÷ 12 = 3.5 feet
Therefore, you will need 3.5 feet of wood to build the rectangular frame.
