The width of the rectangle is 14 cm, its length is 6 cm more than the width. Calculate the perimeter of a rectangle.

To find the perimeter of a rectangle, you need to know what the length and width are. Let’s find the length of the rectangle, knowing that it is 6 centimeters more than the width, which is 14 cm.

14 + 6 = 20 centimeters.

We calculate the length of the perimeter of a rectangle with a length of 20 cm and a width of 14 cm. To do this, we find the product of the number 2 and the sum of the length and width.

P = 2 * (20 + 14) = 2 * 34 = 68 cm.

Answer: 68 cm.
