The perimeter of a sheet of paper is 38 cm. If the width is 8 cm what is the length of the paper?
P = 2L + 2W
38 = 2L + 2(8)
38 = 2L + 16
22 = 2L
? = L
10
To find the length of the paper, we need to use the formula for the perimeter of a rectangle, which is given by:
Perimeter = 2 * (length + width)
Given that the perimeter is 38 cm and the width is 8 cm, we can substitute these values into the formula and solve for the length.
38 cm = 2 * (length + 8 cm)
Dividing both sides of the equation by 2 gives:
19 cm = length + 8 cm
Now, to isolate the length, we can subtract 8 cm from both sides:
19 cm - 8 cm = length
So, the length of the paper is:
11 cm
Therefore, the length of the paper is 11 cm.
