The perimeter of a rectangle is 60cm. It's length is 6cm. What is its width?

P = 2L + 2W

60 = (2 * 6) + 2W

48 = 2W

24 = W

To find the width of the rectangle, we need to use the information given about the perimeter and the length.

The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, the perimeter is given as 60 cm.

Let's denote the width of the rectangle as "w".
According to the given information, the length of the rectangle is 6 cm.

For a rectangle, the perimeter is calculated as follows:
Perimeter = 2(length + width)

In this case, the perimeter is 60 cm and the length is 6 cm. So we can rewrite the equation as:
60 = 2(6 + w)

We can simplify this equation:
60 = 12 + 2w

Next, we isolate the "w" term by subtracting 12 from both sides:
60 - 12 = 2w

48 = 2w

Finally, we solve for "w" by dividing both sides of the equation by 2:
w = 48/2
w = 24

Therefore, the width of the rectangle is 24 cm.
