The length of the rectangle is 6 cm, and the width is 3 cm shorter. Find a re-metric area.

The solution of the problem:
The perimeter of a rectangle is the sum of all four of its sides.
1. Find out what the width of this rectangle is.
6-3 = 3 centimeters.
2. Find out what the perimeter of the rectangle is.
6 + 6 + 3 + 3 = 18 centimeters.
The area of a rectangle is equal to the product of the length and width of the rectangle.
3. Find out what the area of the rectangle is.
6 * 3 = 18 square centimeters.
Answer: The perimeter of this rectangle is eighteen centimeters, and its area is eighteen square centimeters.
