| Let’s find the length of the given rectangle.
According to the condition of the problem, the width of this rectangle is 8 cm, and its length is 23 meters less, therefore, the width of this rectangle is:
23 * 8 = 184 cm.
Find the perimeter p of a given rectangle as the doubled sum of the length and width of this rectangle:
p = 2 * (184 + 8) = 2 * 192 = 384 cm.
Find the area S of a given rectangle as the product of the length and width of a given rectangle:
S = 184 * 8 = 1472 cm².
Answer: the perimeter of this rectangle is 384 cm, the area of this rectangle is 1472 cm².
