The perimeter of the rectangle is 120cm. What sides can this rectangle have?

The perimeter of a rectangle is the sum of the lengths of all its sides. If the sides of the rectangle are a and b, then the formula will look like this:

P = (a + b) * 2.

Since the perimeter is 120 cm, we can find out the sum of its two sides:

120 = (a + b) * 2;

a + b = 60.

Thus, the sides of the rectangle are equal to any numbers, the sum of which is 60. But, it is important to remember that a rectangle is a figure in which one side is larger than the other, which means that the sides cannot be equal to 30 cm.

Examples: 20 and 40, 10 and 50, 15 and 45, etc.
