| According to the condition of the assignment, we determine the area and perimeter of a rectangle if its length is 10 cm, and its width is 2 times shorter.

When it is said that one value is a certain number of times larger, division must be performed. This is how we find the width:

10: 2 = 5 cm.

The perimeter of such a figure, based on the fact that the opposite sides are equal, is calculated by the formula:

P = 2a + 2b = 2 * 10 + 2 * 5 = 20 + 10 = 30 cm.

The area corresponds to:

S = a * b = 10 * 5 = 50 cm².
