According to the condition of the problem, the length of this rectangle is 5 cm, and its width is 3 cm shorter, therefore, the width of this rectangle is:
5 – 3 = 2 cm.
Find the perimeter P of a given rectangle as the doubled sum of the length and width of this rectangle:
P = 2 * (5 + 3) = 2 * 8 = 16 cm.
