Zama - she means I have already answered your question twice.

To find the lengths of the other sides of a rectangle with a given perimeter, we need to use the perimeter formula.

The perimeter of a rectangle is given by the formula:
2*(length + width)

In this case, the perimeter is given as 20 cm. Let's assume one side of the rectangle is x cm.

So, using the formula, we have:
2*(x + width) = 20

Simplifying the equation gives:
2x + 2*width = 20

Dividing both sides of the equation by 2 gives:
x + width = 10

Now, we can solve for the width by subtracting x from both sides of the equation:
width = 10 - x

Therefore, the lengths of the other sides of the rectangle in terms of x are:
length = x (already given)
width = 10 - x

So, the length is x cm and the width is (10 - x) cm.
