1. The perimeter of a rectangle is calculated by the formula: P = 2 * (A + B), where A is the length of the rectangle, B is the width of the rectangle.

2. To determine the width of the rectangle, substitute the values in the formula and find B:

P = 2 * (A + B);

A + B = P / 2;

B = P / 2 – A;

B = 14/2 – 5;

B = 7 – 5;

B = 2.

Answer: The width of the rectangle is 2 cm.
