To find the perimeter of a rectangle, fold the 4 sides of the rectangle.

P = a + b + a + b.

a = 14 cm.

b = a / 2.

Find the width value:

b = a / 2 = 14 cm / 2 = 7 cm.

Now let’s calculate the perimeter of the rectangle:

P = 14 cm + 7 cm + 14 cm + 7 cm = 42 cm.

Answer: The perimeter of the rectangle is 42 centimeters.
