Find the perimeter of this rectangle.
The perimeter of a rectangle is twice the sum of the length and width of that rectangle.
According to the condition of the problem, the width of this rectangle is 2 cm, and its length is 4 cm.
Therefore, the perimeter P of this rectangle is:
P = 2 * (2 + 4) = 2 * 6 = 12 cm.
Find the area of this rectangle.
The area of a rectangle is equal to the product of the length and width of this rectangle, therefore, the area S of this rectangle is:
S = 2 * 4 = 8 cm².
Answer: the perimeter of this rectangle is 12 cm, the area of this rectangle is 8 cm².
