To find the width of the rectangle, we first use the formula for the perimeter of a rectangle, which is given by:

Perimeter = 2 * (Length + Width)

In this problem, we know that the perimeter is 36 cm and the length is 10 cm. We can set up the equation:

36 = 2 * (10 + Width)

Next, we can simplify this equation. Start by dividing both sides of the equation by 2:

18 = 10 + Width

Now, to isolate the width, subtract 10 from both sides:

Width = 18 - 10

Width = 8 cm

Thus, the correct answer is that the width of the rectangle is 8 cm. This satisfies the given perimeter condition when plugged back into the perimeter formula, confirming the calculation is accurate.
