The width of the rectangle is 1 cm, which is 1/3 of its length. find its perimeter and area.

Let’s calculate the length of the rectangle.

a = 1: 1/3 = 1 * 3 = 3 cm.

Let’s calculate the perimeter of the rectangle. The perimeter of a rectangle is twice the sum of its two adjacent sides. P = 2 * (a + b), where a – length, b – width.

P = 2 * (3 + 1) = 2 * 4 = 8 cm.

Let’s calculate the area. In order to find the area of a rectangle, we must calculate the product of the lengths of its two adjacent sides. S = a * b, where a is the length and b is the width.

S = 1 * 3 = 3 cm².

Answer: 3 cm².
