The length of the rectangle is 7 cm, the width is 3 cm shorter. Calculate its perimeter.

The length of the rectangle is 7 cm.
Width – 3 cm shorter.
Let’s define the perimeter of this rectangle. We write down the resulting solution.
The perimeter of a rectangle is the sum of the lengths of all sides of this rectangle.
First, we find the width of the given rectangle.
7 – 3 = 4 cm.
This means that the width of the rectangle is 4 centimeters.
Next, we find the perimeter of the rectangle.
P = 2 * (a + b) = 2 * (7 + 4) = 2 * 11 = 22 cm.
This means that the perimeter of this rectangle is 22 centimeters.
Answer: The perimeter of the rectangle is 22 cm.
