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.
