The rectangle is 14cm wide and 6cm longer than wide. Calculate the perimeter of the rectangle.

To solve this problem, remember that the perimeter of a rectangle is the sum of the lengths of all its sides. Since in a rectangle the opposite sides are equal, then P = 2 * (a + b), where a is the length, b is the width. We calculate the length of the rectangle, knowing that it is 6 cm longer than the width. The width is 14 centimeters.

14 + 6 = 20 centimeters.

Let’s calculate the perimeter of the rectangle.

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

Answer: 68 centimeters.
