Calculate the perimeter of a rectangle if its width is 2 cm and its length is 2 times greater.

We find the perimeter of the rectangle if its width is 2 cm, and its length is 2 times greater. First, we find the length of the rectangle, for this we multiply the width by 2, since it is q times larger. We write down the solution.
2 cm × 2 = 4 cm.
This means that the length of the rectangle is 4 cm.
Next, we find the perimeter of the rectangle. The perimeter of the rectangle is equal to the sum of the lengths of all sides. We write down the solution.
P = 2 cm + 2 cm + 4 cm + 4 cm = 12 cm.
This means that the perimeter of the rectangle is 12 centimeters.
Answer: P = 12 cm.
