A rectangle that is 2 cm wide and 3 times longer. Find the perimeter and area of this rectangle.

A rectangle that is 2 cm wide and 3 times longer. Find the perimeter and area of this rectangle.

From the condition it is known that we are given a rectangle, the width of which is 2 cm, and the length is 3 times the width.

In order to find the perimeter and area of this rectangle, we first need to find the length.

We know that the length is 3 times the width. To find the length, multiply the width by 3 and get:

2 * 3 = 6 cm rectangle length.

Let’s recall the formula for finding the perimeter of a rectangle:

P = 2 (a + b) = 2 (2 + 6) = 2 * 8 = 16 cm.

We look for the area by the formula:

S = a * b = 2 * 6 = 12 cm2.

Answer: P = 16 cm; S = 12 cm2.
