The rectangle is 3 cm wide and 3 times longer. Find the area and perimeter of the rectangle.

To solve this problem, recall the formula for the area of a rectangle. The area of the rectangle is equal to the product of the length and the width. S = a * b, where a is the length and b is the width. The perimeter of a rectangle is equal to 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. Let’s calculate the length of the rectangle.
3 * 3 = 9 cm.
Let’s calculate the area of the rectangle.
S = 3 * = 27 cm ^ 2.
P = 2 * (9 + 3) = 2 * 12 = 24 cm.
Answer: 24 cm, 27 cm ^ 2.
